Hmmm... I'm far from an XML expert, but this is the first time I've heard
of base64 and XML being used together.  It's a good idea, though! It'll
definitely solve the escaping issues, and make the PDF file a valid text
document.

Hmmm... base64 should decode to the exact same binary values that you
started with. I must be missing a step here...   or, wait... do you mean
'[' in the XML tags or in the decoded PDF?

If it's in the XML tags then it's probably a conversion issue.

Losing characters using IBM's parser?  Or your own?

Well, if I wrote it, it's gotta be good! :)  I doubt that iconv() would
cause you to lose characters, though.  What are you translating from/to?
Why do you even need iconv() rather than O_TEXTDATA?

Documentation for what? XML? Base64? The IBM Parser? Expat? iconv?
codepages?

Heh, I envy you. That project sounds like the kind of challenge that I
enjoy overcoming. (My current projects are borrrrrringggg....)
