πŸ’– Jifty::DBI::Filter::utf8 πŸ’–

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. 🫢


✨ NAME ✨

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 πŸ’…


🌸 DESCRIPTION 🌸

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?" πŸ¦‹

Using it as a type specific filter is recommended. like, that's the intended slay. do it that way. ⭐


πŸŽ€ METHODS πŸŽ€

πŸ”₯ 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 πŸ’€
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.

πŸ’œ 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 0xFFFD code point β€” that's the replacement character, the little οΏ½ of it all. it doesn't stop, it just swaps the broken bits out 🌈
  • and it always sets the UTF-8 flag on the value. always. every time. no exceptions. πŸ‘‘

and that's the whole page bestie, you ate it, you understood it, i'm obsessed πŸ’–

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. πŸŽ€βœ¨πŸ’…
