Hi Jan,
U+0105 and U+0119 respectively) are correctly translated to HTML,
Info and plain text,
makeinfo just copies the input in this regard, so it doesn't need any
special support (happily).
but translations to DVI and PDF lack these two characters. I've
tested both ISO-8859-2 and UTF-8. Are you conscious of this
problems?
Yes. The underlying problem is that the basic TeX fonts don't have any
ogonek support (either as a standalone accent or in precomposed
characters), so we don't just get it for free.
I'll see about using the EC fonts, which do support ogonek, as a
temporary workaround. It won't be perfect, but the right way to support
different fonts is still pretty far away.
I'll let you know when I've figured out a patch for you to try.
Best,
Karl
