Hi,
I would expect (*cough*)
\starttext
2\inch
\stoptext
to output something like
2"
with some appropriate typographic symbols following the 2. Instead, I get
a 2 with a large prime symbol down lower than a prime symbol should be, and
then a second prime symbol at about the correct size and at about the right
distance up from the baseline.
\setupbodyfont[pagella]
\starttext
\unit{2 arcminute}
\unit{2 arcsecond}
\blank
2\utfchar{0x2032}
2\utfchar{0x2033}
\blank
2′ 2″
\stoptext
Wolfgang,
thanks very much for that example.
However, while it does show me how to get the glyph I am looking for, I am
left wondering whether there is any way to do it without switching my font
from the default. (And whether \inch is broken, or whether there is an
implicit assumption about font characteristics when using that macro.)
I hate to go to the well too often, but would you care to comment
specifically about \inch and the default font?
(If there is some document whose contents would enlighten me about this,
I'd be happy to get a pointer to it.)
This is a problem for the math team.
The default font "Latin Modern" fakes the symbol with primes but the output
with LMTX is wrong here (old MkIV has the correct symbol) as can be seen
below.
\starttext
% Latin Modern uses \def\inch{\mathematics{\prime\prime}}
2\m{\prime\prime}
% 2\m{^\doubleprime}
\stoptext
Thanks for confirming that there is a problem.
Is it safe to assume that this thread will get the attention of the math
team, so that they will put the issue on their To-Do list? If not, I will
cheerfully file a bug report (at least if/when I find out where such a
report should be sent).

I will talk to Hans about it. The funny thing is that \m
{f\prime\prime} works as expected. So, it is puting primes "on
nothing" that needs to be considered. It seems to work in (many) other
Are inches still used? Anyway, I suppose no mathematician will put a
prime on nothing.
fonts, so, we'll have to look at modern and what is special there.
Does this work ?
