Hi,
When I export a document containing some ZWNJ characters into a PDF document,
the result contains ZWNJ characters, while it should not.

TM->HI: please have a look.

pl->hdu: Good question, should PDF contain ZWNJ or not ?
Comment 7 hdu@apache.org 2008-04-14 15:09:21 UTC 
ZWNJ is supposed to be invisible, so it shouldn't matter. Keeping ZWNJ would probably benefit searching 
for text though.

@PL: there are two possible solutions:
- filtering ZWNJ out when writing PDF's drawtext, which probably causes problems when someone tries to 
copy text from the PDF into other applications
- embed an empty glyph into the font subset instead of the standard behaviour of showing notdef for 
glyphs not known to the font
Comment 8 philipp.lohmann 2008-04-14 15:12:18 UTC 
@hdu: I think substituting the empty glyph would be best; as you said this will
keep the ZWNJ for e.g. copy and paste.
Comment 9 zwnj 2008-04-14 17:02:36 UTC 
Actually ZWNJ can have a glyph, as the font in the screenshots, Nazli, do. 
Because editors can show them when display-control-characters is on.

@hdu, Yes, I think having the character, but using an embedded empty glyph would
be the best solution.

Thanks all, Behnam.
