Math accents set too close to capital

Math accents set too close to capital

[-- Attachment #1.1: Type: text/plain, Size: 784 bytes --]

Hello all,

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

\starttypescript [mathfont]
  \definetypeface [mathfont] [mm] [math]  [palatino]  [default] [rscale=1.0]
\stoptypescript
\usetypescript[mathfont]
\setupbodyfont[mathfont]

\starttext

$\hat{H}$

\def\hat#1{\topaccent{3pt}{0}{90}{\textcircumflex}{$#1$}}

$\hat{H}$

\stoptext

Hi,

Have you tries U+1024 or LETTER CAPITAL H WITH CIRCUMFLEX?

True not all Fonts might not have it and it is TEXT not Math.

Just a thought.

regards
	Keith.

Hi Hans,

Thanks for the response. This is sort of what I wanted, except the \widehat is, well, quite wide. So I hacked it around a bit to put the \widehat from a capital 'I' on top of a capital 'H'. In case it happens to be helpful, the final macro was

\def\hhat{H\kern-0.61em\widehat{\phantom{I}}\kern0.178em}

If I really cared, I wouldn't hard-code those numbers, but since they are in em I'm not really too worried.

Tangential to your issue, but nota bene: instead of $...$ for inline
math, ConTeXt lets you use \math{...} or \m{...}. Which is a bit more
explicit, and can be easier to debug. You might prefer it.

For display math, you really should use \startformula...\stopformula
if you aren’t using it already, because $$...$$ doesn't space
correctly. (Says the wiki. I don’t know it’s still true.)

Cheers,
Sietse

Indeed. And when you use \asciimode, you have no other choice (and
that's a good thing):

  \asciimode
  \starttext
    My #1 is $5

    \math{a^2 + b^2}
  \stoptext

And you shouldn’t use it in math, even Unicode discourages such use.
Accents in text and math are not the same.

I did try that, but it doesn't seem to exist in my font. Besides, I'm inclined to agree with Khaled on math accents. I think that what I'm trying to do shouldn't be that hard, I just want the \mathhat accent to be placed a little higher. Something like \skew in plain TeX, but in the vertical direction.
