Moreover you entry are exactly the same of the last one of adobe code (Appendix 3: OtherSubrs Programs p95) Last but not least according to fonty book: Type Library uses the OtherSubrsmechanism for thehint replacement function and the Flex function. These OtherSubrs procedures work by using some coordinated Subrs entries as well. All Adobe Type 1 font programs that use thesefunctions use them in precisely the same way. As a result, thesemantics of the PostScript language procedures included in the OtherSubrs array have stabilized to the point where the first four OtherSubrs entries and the first four Subrs entries have fixedmeanings. Some Type 1 font rasterization programs such as theAdobe Type Manager software product ignore the PostScript lan-guage definitions of the OtherSubrs entries, choosing internalcode for the particular functions according to the entry number.However, in order to work with the Type 1 BuildChar in Post-Script interpreters, some PostScript language implementation of the OtherSubrs entries must be included in any Type 1 font pro-gram that uses these functions. The PostScript language codeused in Adobe Type 1 font programs is listed in Appendix 3,“OtherSubrs Programs.” OtherSubrs entries beyond the first four are reserved for futureextensions. Each new OtherSubrs entry will be designed so thatit can be safely treated by an interpreter that does not understandits semantics. However, the first four OtherSubrs entries cannotbe so ignored; ignoring them will result in improper execution of the charstring.An OtherSubrs entry is invoked by the callothersubr command.This command takes (from the top of the Type 1 BuildChar oper-and stack down) the index number of the OtherSubrs entry, thenumber of arguments that entry expects, and the actual numericarguments.The complete calling sequence for an OtherSubrs procedure is: arg1 arg2 . . . argn n othersubr# callothersubr pop . . . pop How do you cope with this by rewritting the program cheerio ralf -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Wait ... I am not sure either. Maybe fontfoge *also* contains and
adds this code ... I just found the text in the sources of lmodern.
How ist that done? I thought it was done with fontforge scripts - I

I have no idea and I don't want to care about these things. I will not go
to the lenth of recreating the fonts at build time from any kind of
scripts.

Hi Bastien,
so that was the outcome of the discussion on d-d ... you went ahead
with useless mass bug filing. Well done.

Instead of digging around you *MIGHT* look for *WHERE* this comes from
to help everyone.
This package include copyrighted font hinting from adobe.
Do I understand correctly that we're not supposed to do anything, but
just wait until fontforge is fixed?
Frank, for now please don't do anything. We will see how this
develops. This was a mass bug filing (probably to make release
cycles more enjoyable) and there is no agreement how to deal with
it, at least what I saw on d-d mailing list.
| lm2.003mt1.zip -- Latin Modern source font files for the METATYPE1 package
It is alread lm2.004 ...
The Debian orig.tar.gz doesn't seem to contain the source archive's
contents. I'm not familiar with font generation, but it seems to me
that, in order to be able to generate corrected Type1 files with a fixed
fontforge version, we would need the contents of lm2.003.mt1.zip, e.g.:
It is not a question of fontforge... THe lines mentioned come from
pfcommon.dat
which was inherited from metatype1.
I will contact the GUST people about that.
Does that mean we have one more RC bug, namely that the sources are
incomplete? debian/copyright says:
No. I don't consider the metatype sources necessary, because afterwards
the fonts went through manual hinting and fixing.
