\AA (m-units and \Angstrom)

\AA (m-units and \Angstrom)

[Eckhart Guthöhrlein]

The use of \AA is problematic, in my case concerning the use of \Angstrom 
with m-units. Here come the problems I noticed, and my workaround for those 
who are interested.

Since \Angstrom is defined to give \AA, it can't be used in math mode 
('Please use \mathaccent in math mode'). Furthermore, there is a problem 
with \setupbodyfont[aer]: \AA produces nothing in the output. This is a 
more general problem, not restricted to m-units.

Probably, \AA should be redefined. \def\AA{\Aring} is a possibility, 
\def\AA{\hbox{\Aring}} works in math mode too. But superscripts get placed 
too high, touching the characters of the above line in inline formulas. I'm 
currently using
\def\AA{\text{\AA}}
with the definition of \text copied from the latest publically available 
m-math.tex, enclosed by \unprotect..\protect to make private command 
sequence names accessible.

In principle, I would agree that not using the unit Angstrom would be the 
best solution, but since it is not up to me... And a working \AA is of 
course needed for some languages.

This is probably the best solution. \text should go into the
core anyway (or an equiv. command)

I've now replaced the \AA def by \def\AA{\Aring}

All right, but when the math integration will include the \text command 
some day, I think you should change it to \def\AA{\text{\Aring}}. Nasty 
letter...
