Jifty:...::utf8(3pm)
π Jifty::DBI::Filter::utf8 π
okay bestie, so this is the manual page for Jifty:...::utf8(3pm), and it lives in the User Contributed Perl Documentation section of the perl man pages. yes the name is literally abbreviated like that, no I don't know why, we move on. π«Ά
β¨ NAME β¨
Jifty::DBI::Filter::utf8 β it's the Jifty::DBI UTF-8 data filter, and it is here to make sure your bytes are not lying to you π
πΈ DESCRIPTION πΈ
So the whole vibe of this filter is: it lets you check that you're operating with valid UTF-8 data. That's it, that's the job. Your data gets a vibe check and the vibe is "are you, in fact, real UTF-8?" π¦
Using it as a type specific filter is recommended. like, that's the intended slay. do it that way. β
π METHODS π
π₯ encode
The tea on encode:
- it always unsets the UTF-8 flag on the value, periodt. the flag is gone. bye.
- BUT β and this is the plot twist β if the value doesn't have that flag, then the method goes ahead and checks the value for malformed UTF-8 data, and it stops on the first bad code. like it will not sit there and scroll past nonsense, it halts the second it finds something sus π
no cap, "stop on the first bad code" means exactly that β it doesn't keep going to collect all the problems. one bad code and it's done.
π decode
decode is the opposite energy:
- it checks whether the value is correct UTF-8 data or not, and then
- it substitutes all malformed data with the
0xFFFDcode point β that's the replacement character, the little οΏ½ of it all. it doesn't stop, it just swaps the broken bits out π - and it always sets the UTF-8 flag on the value. always. every time. no exceptions. π

and that's the whole page bestie, you ate it, you understood it, i'm obsessed π
this gorgeous little doc is from perl v5.34.0 and it was dated 2022-06-15 β so yes, it's serving vintage but it's still valid, and honestly? iconic. mwah. πβ¨π
