Re: [dcplusplus-devel] adchpp patch: unicode for lua

[<bla...@ar...>]

The first libary is smaller and extends the standard string libary with:

string.subutf8(string, start[,end]) substrings, UTF-8 aware=20
pos, char =3D string.nextutf8(string, orig_pos) returns the char at orig_po=
s and the next char's position in pos.=20
for i, char in str:nextutf8(orig_pos) iterates through the string, starting=
 at orig_pos.=20
pos =3D string.seekutf8(string, orig_pos, n) returns the position orig_pos,=
 N characters forward (or backwards, if N negative).=20
char =3D string.utf8char(code) returns the char the code of which is code.=
=20
code =3D string.utf8code(char) returns the code of char (UTF-8 character).=
=20
len =3D string.lenutf8(string) returns the length of string in UTF-8 charac=
ters.

and can be used when one has something exactly to count (for example for ch=
ecking the length of nicks, counting words and chars of chats)

The slnunicode libary is much bigger and adds the table "unicode.utf8" whic=
h is similar to the string libary.
When one replaces for example str:match(...) with unicode.utf8.cbb_match(ms=
g, ...) it should do the same as before and works also for utf8. (i did a m=
istake and renamed match to cbb_match)
I think it should be used for simple hubcommands like +reg nick or for thin=
gs like bad word filters.

The first libary is maybe optional when one uses slnunicode.
