Allow diacritcs in label

[EtienneDG]

First, great bot ! 👍

Could it be possible to support diacritcs in label ?

For instance, this doesn't work :
5dF éloquence

But this does :
5dF eloquence

Thanks.

I'm looking into this. I've got it working on my test bot but am having trouble with it in production. Hopefully I'll get it working soon!
