add iconv to suport multi-language #14

hzlooker · 2019-01-31T13:53:07Z

Hi,guys,
the function
int GdConvertEncoding

(const void *istr, MWTEXTFLAGS iflags, int cc, void *ostr,
MWTEXTFLAGS oflags)
int the file devfont.c can not convert a multi-language UTF8 string to UTF-16 string but ASCII.
so I add the iconv lib to make this function can convert multi-language UTF8 string to a right way.
maybe someone need it. by the way in config need add libiconv and libcharset

devfont.c

devfont.zip

Hi,

Thanks a lot! Can you attach the devfont.c file directly, it didn't show well above. I can then look at it and merge it into the repo.

What languages did you test this with?

Regards,

Greg

The problem remains only with the leveling of the text, I don’t even know which way to look like this is GrText, but I can’t find something.
