If the character speaks another language, that's fine really. I have a character that speaks another language and I enjoy adding that language here and there, but it's a canon language and I provide translations. Having a character speak a language they don't in canon, just so one can post in that language with no translation provided... It gets on my nerves. I want to know what his/her charcter is bitching about. I want to be sure the RPer isn't saying something about the rest of us.
