For what it's worth, Mac character 202 (U+00A0) is neither thinner

And it's not particularly difficult to include all the different spaces if
that's what you want. In this instance I particularly wanted to get rid of
option-spaces, not regular spaces. I don't understand why AppleScript was
deciding for me that, if it's Unicode, I "really" must have meant all
spaces. I didn't mean all spaces, I meant option-space, and that's why I
specified the somewhat obscure ASCII character 202 and not the 'space'
constant. The distinction is honored for 'string'; why not for Unicode?
