Accented characters in tags

Is there a way to have the search function find items whose tags contain accented characters (as it is often the case in European languages).
So far, even in the version 8, tags can be saved with accented characters but the search function does not see them.

you could put elastic-search for this purpose, otherwise you could upgrade to cells if you don’t have lots of data, pydio cells search engine has this function with the special chars.
