hm, but square brackets can interfere with optional args where [] don't
nest well (tex does not treat them as delimiters as it does {}

using {} would probably have been safer or maybe () (round ones) since
afaik these are seldom used for delimiting args; or maybe just

file:somename

anyhow, if it's filename stuff i can probably just feed the [] deep down
in context to the xetex font command

will think of something

please forward to jonathan since his mailer an dmy mail server don;t
like each other -)
