RFC 8140: The Arte of ASCII: Or, An True and Accurate Representation of an Menagerie of Thynges Fabulous and Wonderful in Ye Forme of Character π¦
okay bestie, this is RFC 8140 π written by A. Farrel from Old Dog Consulting. It's an Independent Submission in the Informational category, dated 1 April 2017, with ISSN 2070-1721. The title block doesn't list anything it obsoletes or updates, so nothing is being replaced here. πΈ
Abstract β¨
Ever since Gutenberg discovered and patented ASCII and the corresponding "Courier New" font with its now-famous "ten" point size, artisans and artificers have striven to represent their views of the world in print. π¨οΈ
Similarly, starting from Darwin's discovery of the hippogriff and his subsequent registration of the creature as an International Trade Mark, men (and some women) have struggled to catalog the fabulous variety that is called "nature". π¦
This document supplies a number of representations of all manner of things (both elemental and hypothetical) supplied by some of our best collectors of curios and delivered in a manner that may well be reused by the cunning document author. π§

Once upon a time, in a land far, far away, where princes were available to those who knew how to kiss, and frogs could be picked up by the handful and were sold in brown paper bags at the shop on the corner of your street, there was an impish discovery made by the appropriately named Johannes Gensfleisch zur Laden zum Gutenberg. His name, it turned out, was coincidentally fortuitous, because when he uncovered the Gutenberg Press he was able to claim it as his own. π
Amongst Gutenberg's better known discoveries were the ten point font, the Courier New Font (which he is supposed to have found growing in a hedgerow close to his cottage), and the ASCII character set. All of these have been embraced as comforting and warm blankets by the engineers of the IETF as they embark on expeditions to plot the desolated wastes of the Internet. π§£
Although the RFC Editor has recently dragged the IETF kicking and screaming into the twentieth century [RFC7990] [RFC7996], there is a yearning among all right-thinking Internet architects to "keep it simple" and to return to the olden days when pigs could be given thrust without anyone taking undue offence [RFC1925]. π· This document attempts to address that yearning by demonstrating the full wonder of the natural world in vivid two-dimensional representation and a colour palette that would put even the august L. S. Lowry to shame. π¨
Readers of this document are encouraged to be familiar. π
2. Beasts of the Land π¦
"Many and wonderful are the beasts of the land" wrote the poet. And he was right in some ways. πΏ
Of these many beasts, the most fabulous are the Troll and the Unicorn. Here are reproduced representations of sightings in the field. πΈ
2.1. The Troll πΉ
The troll is an evil beast that frequently appears around the IETF. It feeds alternately on passing goats and cookies, but it prefers above all things the taste of distress, especially that expressed in email. πͺπ
Trolls should be shunned and never fed. Stories about them being sensitive to water or light are unsubstantiated, but it may be true that they can be pacified with alcohol. π·
The chief weapons of a Troll are its sharp tongue, its blunt phrasing, and its total disregard for doing useful work. π

Figure 1: The Troll at Feeding Time2.2. The Unicorn Rampant π¦
Many things in the IETF rely on majick. Without pixie dust or other artful contributions from the world of faerie, it is unlikely that the Internet would work at all. β¨
Software Defined Networking (SDN) is a concept whereby complex and devious networks may be subjugated to the will of a sorcerer (or an opensourcerer as they are sometimes know). Fundamental to the body of an SDN is the Path Computation Element (PCE) [RFC7399]. Essential to the proper function of the PCE is the Unicorn that roams the dark wood of the Traffic Engineering Database, rearing up and spearing unwitting paths on the horn of its intellect. π²
Unicorns, it is claimed, can only be captured by the pure of heart who have never operated a real network. π

Figure 2: A Unicorn in Rampant State3. Creatures of the Deep π
"Not all that crawls upon the land can rival the creatures of the deep," said the great ethnographer and philanderer. And how often it has been observed that he was both wise and drunk. π₯΄
The things that slide below the surface of the water remain hidden to most of us, a mystery no less than the ways of the elliptic curve. Most elusive of all is the Loch Ness Monster; most peculiar is the Marlynne. π
3.1. The Loch Ness Monster π΄σ §σ ’σ ³σ £σ ΄σ Ώ
So rare are the sightings of this beast that we must count ourselves lucky to have presented here a very real etching, collected at great expense from a native Scott. π€©
The Loch Ness Monster appears most often on dark nights or in heavy storms, when the only thing that parts the fog is the rain that lashes your face. Thus, the creature is most often visible when it can be least well seen. In this respect, it is most like clear text in an RFC, which is most easy to read and comprehend when it is least written. π§οΈ

Figure 3: The Loch Ness Monster On a Calm Day3.2. The Marlynne or Sword Fishe π
Getting to the point is not always something that is practised in the IETF. But there is one beast that Roams the Deeps and Never Sleeps: The Marlynne, when hauled from its roost by an unsuspecting fisherman for delivery to his equally unsuspecting fishwife, has often been mistaken for a very angry mermaid [MTFTW]. Do not mistake its sharp wit for a valid argument. π§ββοΈ
As can be seen from the rendition here presented, the Marlynne is happy in its work. π

Figure 4: The Sword Fishe - An Happy Fishe4. Spirits of the Air βοΈ
Cloud is the latest buzz for the trendy hipster, active in networking. But be careful not to let your feet get off the crowd, lest your head become implanted somewhere it shouldn't be. π
4.1. Ze Vompyre π§
okay so the scariest creature in this whole zoo is the vampire π, bestie. it drains the blood out of any good idea until it shrivels up or gets turned into a problem statement I-D π. it's giving more terror than the Old Timer who sucks all the air out of a room with their beloved Process Discussion. it's also more frightening than the RFC 2119 Usage Debate of Doom π
the vampire bat gets mixed up with its third cousin on its mom's side, the fruitbat π and honestly the fruitbat is just as evil. it'll strip whole plates of fruit off the refreshment table and leave only celery sticks for the latecomers π
data that a vampire has nibbled on can end up with some of its most precious bits corrupted and falling off π the only real protection is putting garlic in the metadata or overhead of a packet π§β¨

Figure 6: A Fine Mirror Showing The Reflection of a Vampire Bat4.2. Avian Carriers ποΈ
the Avian Carrier [RFC1149] is the most famous of them all, even more iconic than the Thrusted Pig [RFC1925] and the Infinite Monkey [RFC2795] π
this sky scavenger comes in a bunch of bright colors π maybe that's an evolutionary glow-up that lets a hunter tell the carriers apart and drop the weakest ones π or maybe it's a warning to the predatory Buphyres, so they leave alone the carriers the flock finds most important π¦

Figure 7: A Flock of Avian Carriers with a Nest of Packets5. Man-Made Structures ποΈ
"Man has become God and shapes the world at will," said a slightly disgruntled theologian π and honestly, who would dare argue with that when they're trying to escape the convo in time to get home for dinner? π
5.1. Bauhaus π¨
when Laura Ingalls Wilder was just starting out on her cover designs, she agonized over what shade her little house should be π she narrowly avoided madness thanks to the timely intervention of Professor Kandinsky, a prominent Moscow lawyer π§
it's often claimed that new art forms are needed before IETF publications can include colors. Figure 8 totally proves that's a fallacy π

Figure 8: The Fundaments of Bauhaus5.2. The Gingerbread House πͺ
so many stories have been told about how young Hans and his sister, the equally young Gretha, ended up abandoned in the woods [TFTW] π but it may have been Herr Grimm and his eponymous brother, Herr Grimm, who first recorded the existence of a house made of gingerbread (with all the trimmings) ποΈβ¨
be warned that packet tracing with breadcrumbs will usually fail because the avian carriers like to keep the forest floor tidy (Section 4.2 ποΈ

House6. IANA Considerations π
IANA might consider setting up a registry for Figure 8 to track which colours get assigned to which shapes π
7. Security Considerations π
stone walls don't make a prison, and iron bars don't make a cage, but they do help 𧱠so with that in mind, our elders always encourage us to stay mindful of the security and privacy of our eternal souls πΌπ
7.1. A Private Key ποΈ
keys that are shared are keys that other people have π¬ if someone else has a key, they'll use it. if you have a key, you'll probably leave it in the lock or drop it in the street. so basically, keys are a security vulnerability π

Figure 12: A Backdoor Left Conveniently Open8. Manageability Considerations π¦
some of the wild beasts in this tome are best kept confined to a managerie πͺβ¨
9. Morality Considerations π
Okay so, following the advice in [RFC4041], this section looks at how this document affects public morals. π Yes, it's a whole section. Yes, I'm serious. π
Popular opinion still says moral values are sliding and degeneracy is on the rise, and you can check that with reliable metrics, so it's not just vibes. π Just look at the total chaos around the True Use of Language in RFC 2119 [RFC2119] and you'll see the populace is truly debauched. π
9.1. Likelihood of Misuse by the Depraved π
Be careful, bestie. ASCII could fall into the hands of some very disreputable characters. π
9.2. Likelihood of Misuse by the Misguided π¨
Warning to the kids: don't engrave self-portraits in ASCII-art and share them with your friends as woodcuts or in other modern media. π¬ Remember, a picture, once made, lasts forever. π
9.3. Likelihood of Misuse by Corporations π¦
The very idea that someone might patent unicorn DNA is, of course, unthinkable. π ββοΈ Large companies only have our best interests at heart, obviously. π«Ά
9.4. Oversight Facilities π
Adequate oversight of all things is performed by the RFC Editor. Who has a higher moral compass or a better sense of directional values? Exactly. π
9.5. Other Ways of Doing Things π
Radical and subversive cliques, like the heretics Georges Seurat and Paul Signac, can also be represented in ASCII art. π¨ However, doing so will, in almost every case, exceed the 72 character width limit that all right-thinking people use. It must, therefore, be avoided by everyone who doesn't want to be doomed to spend eternity in a dark corner with only dial-up access. ππ
9.6. Concern for Wildlife π¦
Never was a truer word spoken than when it was said that a duck may be somebody's mother. π¦π₯Ή See also Section 4.2. π¦
