Because a font name is only one or two characters unless it is a `long
name in parentheses'.  A regexp is

    /^f[\x20\t]*
        (
        \([^\x20\t]\)
        |
        .[^0-9\x20\t\n.]?
        )$/

So it's fCW and fIw.

See line 850 in src/preproc/tbl/main.cc for more detail.

Cheers,


Ralph.
