[NTG-pdftex] escaped spaces in \pdfescapestring

[Pawel Jackowski]

Pawel:
>>what is the reason to escape spaces and newlines in \pdfescapestring?

Heiko:

Yes, you're absolutely right.

I've just encountered a problem. Shouldn't \pdfescapename also escape 
`%' character?

\escapechar=-1
\setbox0\hbox{Aqq}
\immediate\pdfxform
    attr {/\pdfescapename{M\string\%Y} /Val}0
\pdfrefxform\pdflastxform
\end

This produce corrupted output
