Hello all,

Playing with define/setup/set characterspacing, I have come across some odd, perhaps buggy, behavior. This applies to both MkIV 2020.11.19 11:23 and LMTX 2020.11.19 11:28.

The problem is that character spacing is not effected for the left side of the comma character. It is handled as expected for other characters that I have tested, but I have not performed extensive tests.

Example code:

    \definecharacterspacing[Test]
    \setupcharacterspacing [Test] ["002C] [left
    =.25,right=1,alternative=1] % ,
    \setupcharacterspacing [Test] ["0065]
    [left=0.5,right=1,alternative=1] % e
    \setupcharacterspacing [Test] ["003B]
    [left=0.5,right=1,alternative=1] % e
    \startTEXpage[offset=1em]
    abc; def, g

    \setcharacterspacing[Test]abc; def, g
    \stopTEXpage

remove the space between "left" and "="

I should have know better than to copy as I did from the source code without analyzing it sufficiently! In typo-spa.mkiv I found:

\setupcharacterspacing [frenchpunctuation] ["003A] [\c!left =.25,\c!alternative=1] % : ...

I see (now) that the space disappears when the \c!left macro is processed. Mea culpa. I owe you a beer.
