Signu issue : accentuated characters fails

[Italemyae]

Hello,

Thanks for the job.

I have an issue with an user name Frédéric#xxxx
I double-check, discord shows accent but when i tried to type @Fré there's no result.
If i type @fre autocompletion say @Frédéric#xxxx

So there's probably a trick on discord itself.

Btw, in the webUi i try to add myself both @Frédéric#xxxx and @frederic#xxxx without any results.
Other guys are correctly tagged/signed-up but not Frederic.

Is it any workaround from you side ?

Thanks you for this wonderfull bot,
Ita
