Peter,

RFE was probably right. But its moot for 1.6 as we are in the very final
stages of
stabilising the release so unless it can be shown to be a regression
(something that
used to work in 1.5 but now doesn't) it too late.

Peter:

Please file bugs on both issues.

There are a few characters we special case when converting to glyphs -
tab, cr, lf are it in the ASCII range, and we also filter bidi control
characters and some other formatting characters.  Everything else goes
through the regular font CMAP, and if the font maps it, most of the time
it will provide the missing glyph for these characters. If the font
doesn't map the character at all, we use the missing glyph.  The missing
glyph typically looks like an empty rectangle.

Currently the characters we map ourselves are the following.

    0x0009, 0x000A, 0x000D,
    0x200C, 0x200D, 0x200E, 0x200F,
    0x2028, 0x2029, 0x202A, 0x202B, 0x202C, 0x202D, 0x202E,
    0x206A, 0x206B, 0x206C, 0x206D, 0x206E, 0x206F

You'll note we don't currently handle ZERO WIDTH SPACE (U+200B)...

This is an implementation detail, of course, and some vendors (Apple, in
particular) probably do something different.  This is just FYI.

Doug,

I think I made a little mistake. I've put both of these in as RFEs,
which I (now) assume means they won't be considered for 1.6. Should I
change these to bugs when the opportunity arises?

Peter
