Big-Ip Edge Client specials characters problems

Could you give a screenshot of how you're typing the french characters? Are you copy/paste them directly (unicode) or are you using HTML entity encoding? What version of big-ip do you use?

Could you provide the text of the error you received, or information about how to reproduce the error?

Here's a discussion about entities vs unicode:
