I am missing something. I tried the following (with the alpha,
cont-new.tex contains the new definitions), but get not accent with
the following code.
\startmathcollection[euler:texnansi]
\definemathsymbol [breve] [accent] [tf] [15]

I am restarting one of my old threads, so please be patient.
To restate the problem, some accents are missing from euler font. Adam
suggested using a hack along the lines of latex to pull those accents
from the text font, later Hans posted some code that took care of
encoding and stuff. Hans added the code to cont-new.tex with a example
usage in the comments.
I could never get the example to work.
Hans, the code in cont-new.tex is slightly differnt from the code that
you posted on the ML. The code on the ML works, while the code in
cont-new.tex does not.
The attached file compares the output of the code in cont-new.tex with
the code posted on the ML. Can you look into it to see what is going
on. Since euler is the only incomplete math font, the definitions for
all the accents can be added to math-eul.tex.
