Well, I was thinking of fonts with a standarad character set which
don't provide capital accents anyway.  If you have them, fine.
If not, replacing them by normal accents is a reasonable approach.

Well, yes.  Actually, in textcomp.mtx endashes are used for this
purpose.  I was just a little confused when I said hyphens.

I didn't try this yet, but that a might be one way to do it.  The 
real problem, however, lies in determining the proper shift amounts.
(Same problem as for faking double square brackets.)

Well, this just means that if you happen to have 8x (URW) fonts, you
will get a lira sign, otherwise not.  If you want to reduce TSA/TSX 
to the Adobe sets and nothing else, you probably have to throw it out.

Cheers, Ulrik.
