I'd say open a bug and attach your pull request. It's worth looking into.

Does anybody have any thoughts on this? I'd like to submit a bug & a
pull request but OTOH something this low level could have subtle
implications and I'm concerned I don't know enough about potential issues.
Thanks
John

Subject: [qooxdoo-devel] Unicode characters and qx.lang.String.trim
Hi
I came across an odd bug today -- after getting some text from DOM
nodes and then passing it to qx.lang.String.trim(), what I thought was
an empty string had a length of 1. It turned out to contain unicode
character u+ffef, also known as "Zero Width No-Break Space" - I found
an article [1] that goes some way to explaining it and also mentions
other unicode space characters u+FEFF, u+200B, u+200D, and u+2060.
At the moment qx.lang.String.trim, trimLeft, trimRight, and clean only
remove characters that match the \s regex, but should this be expanded
to include other Unicode whitespace characters? Would it be
detrimental to Qx users if it was changed?
