Japanese language (long) texts get some improper line break when some half-width spaces (“ ”) are used in it.
Chinese got the same issue since it doesn't put spaces between words.
A full-width space (“ ”) doesn't have the issue.
I found out that hair space (U+200A) doesn't have this issue and have the same width with regular space, so possible to use to do a workaround.
We don't have our own whitespace detection code.

Half-Width space is U+FF00 is not considered a whitespace character
Thin space is U+2009 is a whitespace character
I don't know which specific character you are talking about in the initial ticket.
I was talked about U+0020, which is the character that will be written when we press the space bar on a keyboard.
...Am I right? Not really good with those Unicode things.
