When entering the @ charachter Confluence automatically starts to filter for other users which is a cool feature. The feature could be improved by ignoring those special characters when typing and filtering (as it is for example not so cool to type those on a english keyboard). For example:
We have a user with the name 'Céline'. When I do enter know 'Cel' Confluence does not propose me 'Céline' as it appears that the characters must match exactly. It would be nice that Céline gets proposed even though I am just entering a normal e instead of the é.
I am not sure if my proposal is clear but in SQL this is related to the collation.
Thanks for listening and have a nice day!
