Chinese LOCALE and string.sub

Hi all,

someone knows why this is happening ?

Is Lua able to parse the Chinese language string or this is not a conventional string so the string.sub is not the right thing to do !?

Thanks for any input and Happy New Year to everyone :)

P.s.
We was discussing here:

string library assumes single byte characters, Chinese are multibyte.

You need a library like UTF8 in order to do some of these operations.

Hi Dridzt,

thanks so much for your reply and suggestion.

I imagined it was related to a multibyte problem but didnt know how to solve :)
Now I know it could be done with this library. :)

But because I am not so sure that the first char I get from a multibyte locale string means what I want I have adopted a mixed approach solution :)

For single byte locale string I use the normal string.sub , for multiibyte I prefer to provide (if any) a preset string in localization.lua.

Lua Code:

fort1 = string.sub(C_ChallengeMode.GetAffixInfo(10),1,1)
tyra1 = string.sub(C_ChallengeMode.GetAffixInfo(9),1,1)
if GetLocale() == "zhTW" then
   fort1 = L["F"]
   tyra1 = L["T"]
end
... bla bla

Btw thanks so much for your kind reply.
