Terminal link detection doesn't handle words of non-english characters

Testing #96299

touch '我是学生.txt'
touch '我是很酷.txt'
ls

If I hover one of those names, only one character is highlighted. I figured words would just be delimited by whitespace and some characters like ()[] etc

Good find, I think it's happening because to the right of each wide char is an "empty" char which is probably being interpreted as a space

Fixed this but there is still a glitch where the underline will show on an extra character, this is in xterm.js deferred to xtermjs/xterm.js#2887
