Operating System (Linux/Mac/Windows/iOS/Android): macOS
Delta Chat Version: v1.36.1
Expected behavior: Writing in a hashtag containing a set of continuous word characters, including any diacritics, has the client recognize it
Actual behavior: Writing in a hashtag with diacritics makes it recognize the tag only up to the point of first non-ASCII letter
Steps to reproduce the problem: Write in e.g. "#tłumaczenia" in your chat message, send it, see the resulting tag hyperlink ending early. Click on it, and it causes the search to go to "#t" rather than the entire word ("#tłumaczenia")
