Tthe file has been generated by a perl script (unicode-char-prep.pl)
with the help of the informations in
http://unicode.org/Public/UNIDATA/UnicodeData.txt. 

The perl script says "# \catcode = 11 for everything with GC=L*"

and the unicode-data entry for e.g. the mathematical P is:

1D443;MATHEMATICAL ITALIC CAPITAL P;Lu;0;L;<font> 0050;;;;N;;;;;

So I would say it has catcode 11 because unicode says it is a
letter.
