I'm afraid not. All I got was an ugly, red <braceld> when I typed C-q,
braceld, <enter> in math mode. My rubber-cmex.enc file has the following
appended to it:
122 "braceld" "bracerd" "bracelu" "braceru"
Also, this does not solve the problem of the txexa font wherefrom I need
the brace extension character. An overbrace consists of the followings:
braceru bracelu bracerd
v v v
braceld -> .- ----<-txexa #32->---- -' '- ----<-txexa #32->---- -.
So, basically, I also need txexa. Here's what I've tried so far:
File txexa.enc:
32 "bracext"
file math.enc:
...
[txexa]
...
All this got me when I typed bracext was a really weird symbol, and it
didn't say
"Please wait, generating txexa<some-number>.<some-extension>"
Also, since the symbol looked like a <nsucccurlyeq> rotated Pi/2, I
tried to click on the menu with the <prec> symbol to try to identify it,
but at that point, TeXmacs crashed with
Fatal error: Font not found in 'math_font_rep::search_font'
Creating a file called cmex.enc with the line
122 ...
did work, but produced the wrong symbols.
Conclusion: This is not working.

Actually, I was thinking about using virtual fonts and Scheme functions
such as (glue ...). I was thinking about making it just another
character, to be used with (make-wide ...) and (make-wide-under ...).
However, if I can't get to the point where I can see these symbols, I
cannot proceed further on any path :o(
