Summary0000852: Ignored italic correction in math with lua(la)tex format when catcodes are set to letter.
DescriptionLuaTeX, Version beta-0.76.0-2013062820 (rev 4627)

As can be seen in this question
http://tex.stackexchange.com/questions/131717/how-can-i-avoid-that-a-functions-argument-touches-the-brackets-using-unicode-mat
the problem discussed in the thread starting with http://www.tug.org/pipermail/tex-live/2011-October/030295.html still exists in the luatex binary.

I couldn't find a issue tracker for the problem so I'm now adding it so that it doesn't get lost.

It is obviously not a pressing issue as a work-around is easy. One simply should avoid to set the catcode of some math chars to 11.

It doesn't look as if the problem has been resolved: The italic correction stil depends on the catcode of the math italic chars. Here a context variant of Khaleds example that demonstrates the issue:

\starttext

$$P($$

\catcode`\^=7
\catcode`\^^^^^1d443=11

$$P($$

\stoptext


The second P (with catcode 11) is much nearer to the parenthese.

there will be:

\mathoption alwayscharitalic 1 : always italic so no checking (with new fonts)
\mathoption alwayscharitalic 0 : old behaviour with catcode 11 check

so, a sequence of chars by default now gets italic correction i.e. P <ic> P <ic> P <ic>
