I'm trying to typeset 'H' with a circumflex (or hat) in math mode, but the result is rather ugly when not using latin-modern. I've tried to redefine the \hat macro to move the accent up a bit using \topaccent: is this the best approach? Having to nest '$' does not seem right at all. (Also, for some reason although I find \mathhat in enco-ini.mkiv, when I try to use it I get undefined control sequence.)

Thanks,

Michael
