[erlang-questions] 回复: ejabberd translate crash

Hi,

I’m not really familiar with ejabberd in particular, but I can think of two possible ways to fix your problem:
change the iolist_to_binary call to uncidoe:characters_to_binary, which will take care of utf8 encoding the unicode code points
change the translation file (el.msg) to contain the translations as binaries instead of strings (<<“…”/utf8>>)

I’d prefer the first solution, btw.

Regards,
Daniel
