[tex-live] Latin Modern bug in lm-texnansi-os.enc

[Taco Hoekwater]

Hi Jacko,

On the ConTeXT mailing list, Idris posted some messages because he was
trying to use oldstyle numerals in the latest Latin Modern release,
and was experiencing two pretty big problems:

   * really bad kerning around the oldstyle numerals
   * pdftex generated errors for the typewriter fonts, complaining
     "glyph `one.oldstyle' undefined" etc.

The implementation of 'automatic' oldstyle numbers in ConTeXt uses a
set of encoding files that used to ship with LM (lm-xxxxxx-os.enc).
By way of a map file fragment, this allows to switch the fonts
'en masse' from lining to oldstyle (and back) without the need for
special metric files, which is a pretty nice feature.

Those encoding files now apparently obsolete: they still refer to
glyphs named e.g. `one.oldstyle', whereas in the current release of
the LM fonts it really should be `one.taboldstyle'.

While writing a bug report, I noticed that these encoding files are no
longer in the font distribution (They are still included on texlive2007,
but I don't know if anybody  except ConTeXt attempts to use them).

Is this trick to get oldstyle now officially unsupported? That would
be a shame, because there are no oldstyle-using TFM files in the LM
distribution either ...

Best wishes,
Taco
