Font selection problems
When using compatibility mode, it is possible that you will find
problems with font-changing commands in some old documents. These
problems are of two types:
- producing error messages;
- not producing the font changes you expected.
In case of error messages it is possible that the document (or an old
style file used therein) contains references to old internal commands
which are no longer defined, see Section
for
more information if this is the case.
LATEX 2.09 allowed sites to customize their LATEX installation,
which resulted in documents producing different results on different
LATEX installations. LATEX2e no longer allows so much
customization but, for compatibility with old documents, the local
configuration file |latex209.cfg| is loaded every time LATEX2e
enters LATEX 2.09 compatibility mode.
For example, if your site was customized to use the New Font
Selection Scheme () with the |oldlfont| option, then you can
make LATEX2e emulate this by creating a |latex209.cfg| file
containing the command |@oldlfont|.
Similarly, to emulate with the |newlfont| option, you can
create a |latex209.cfg| file containing |@newlfont|.
