Summary: Expandable \pdfstrcmp, \pdfescape*, added \pdf(de)escapehex
Initial Comment:
Hello,
the result of last weekend is a patch that
makes \pdfstrcmp (based on Harmut's work)
and the \pdfescape* commands expandable.
Thus \pdflastescaped* are not needed
anymore.
I could remove the dependency
on a limited buffer by copying the destination
strings directly in the string pool above the
source string.
Also the patch adds the fixes of bug 369.
Fourth I add \pdfescapehex and \pdfunescapehex
that implements encoding and decoding for
hexadecimal strings:
* Strings can also be given as hex strings in
angle brackets.
* Safe method to store and read string data to
auxiliary files without worrying about catcodes,
unmachted curly braces, ...
* Help in handling UTF-8/Unicode or other hex coding
stuff.
