[XeTeX] zhspacing interferes with latin apostrophe (2019)

[Axel Kielhorn]

Hello!

I've been contacted with a problem report involving zhspacing and a Unicode Apostrophe:

The Apostrophe is replaced by a Chinese character, which looks horrible in context.
When I use a ' and Mapping=tex-text the correct character is printed.

The document enclosed does not include Chinese text, just loading zhspacing is sufficient to produce the error.

If I put zhspacing into a group, everything is fine, I'm just wondering why it acts on non-chinese text. (Well, it doesn't know the text is non-chinese.)

My TL2010 is about a week old:
