which is probably why it was so easy to model UTF-8 on a napkin
which is probably why it was so easy to model UTF-8 on a napkin
Pwhich is actually how it was invented
Mbetter than the best thing i've done on a napkin
Tapparently "str".chars().nth(1) works 
Aall i wanna do is go
why is this so hard
if string[1] == 'c'why is this so hard
Ait does yes
Abut that also iterates through the entire damn string
Lbecause langauge is hard
Aevery time you call it
Lits just not that simple
Mof course it was a sad day for everyone using the "extended ASCII" encodings
Mor non-ASCII
Tsimple, just don't

Mstep 1. delete rust
step 2. use c#
step 2. use c#
Pwow that codegen is laughable https://godbolt.org/z/zv9McWTEK
Astep 3. delete c#
step 4. return to c
step 4. return to c
Pthat's with maximum optimisation
Mwhat the fuck
Ayep
Mthis shit is in firefox?? 
Ay e p
Athe best way to do this is genuinely to allocate an entirely new damn array
Pmarginally better https://godbolt.org/z/87vjddjY3
Lnow get the 2nd char in a C string
Awhich just is major pain
PMajor Pain 
Mdo what all c++ programmers do and roll your own string type
Asimple,
and if you have a japanese character then just
just
give up
perfect!!!
thing[1]and if you have a japanese character then just
just
give up
perfect!!!
Mthere are algorithms for this
Lcorrect
Punrelated but i found that someone made a SIMDified masked v-byte encoding
P(where one bit is a marker bit for the rest of the data)
Min english, four-eyes /ref
PMwhat
Ai'm convinced making simd work well is akin to magic
Mis vbyte a variable-length integer
Pyep
Moh okay
Aooh
Mthat explains a lot
Mlooked it up and just got bitcoin stuff
Mwhat is it.. for
Moh, storing packed arrays of ints and operating on them
Lin zig the compiler just gives you some nice vector types and functions and does all the hard work for you :^)
Lyou can do
@Vector(8, u32)rust has the same, and it's hit or miss
Lyeah im sure for optimal perf its not perfect, but in general it gives good results and is a million times easier
Lyou can always inline asm the raw instructions
Tban the asm
