I've been trying to fix the invisible name bug (
https://github.com/ValveSoftware/halflife/issues/1343) since days and after reading
http://www.tamasoft.co.jp/en/general...e-decimal.html, I've came up with a plugin to prevent players from using all unicode character in their names by allowing only character from 32 to 126 (see second link for more info).
If possible, I'd like to allow all unicode character in names except ones that are invisible. I've tried many other ways including checking for the strlen but it doesn't return 0 for the invisible unicode char. If there are no other ways to fix it, do any of you guys by any chance knows which unicode are visible and which are not visible?
