I am trying to provide the characters W-circumflex and
Y-circumflex for a user who deals with Welsh (Funny, this seems
to have been overlooked by all the ISO font work...)

I have been playing with the Times fonts and the associated afm
files, and I know correct looking offsets for printing the
circumflex character on top of the W,Y,w and y characters (in
the non-italic fonts), so all is looking fine for making these
composite characters out of existing Times characters.

But....

How do I define a new font that extends the existing
Times-Roman by the new composite definitions?  Times-Roman is a
builtin font, so it doesn't have a BuildChar routine, so I
can't just stuff in some extra defs and a new Encoding vector.

Times-Roman also lacks a CharBBox directory, so I won't know
what to say for the bounding box of each of the unchanged
Times-Roman characters (though I do know my new ones, of
course). Will I really have to go through the grotesque process
of "charpath pathbbox" on each one (it would be easier to copy
in the data from the afm file)?  Do I have to do a

        /Times-Roman findfont 1000 scalefont setfont

for every call to BuildChar?

Once I have created this font (I'll manage it somehow, even if
the answer is totally gruesome!), I want to make it useable by
A.N.Other Wordprocessing package, so I will also need to know
a format I can use to get the same treatment as the Adobe
downloadable fonts - where can I get this information?


All assistance gratefully received - I promise to post the
resulting font to comp.fonts so any other Cymruphiles out there
can use it.
