is there a way to stop texmacs  to treat multi-letter strings in math
mode as operators?

I'm writing a geometry book
Consider this situation

"Let $ABC$  a triangle, and suppose $A$ is right..."

(of course I'm using $ $ to represent in ascii the mathbox
Now, texmacs makes ABC to be upright whereas A shows up slanted. So I
get ahge problem of consistency, since everytime I refer to points or
single-letter geometric objects, I get slanted, and when representing
segments or polygons I get upright, and this is becoming a problem

When I started I  tried not to pay much attention to it, but now it
just looks unprofessional and unconsistent, sicne everywhere I get a
mix of slanted and upright representing the same objects.

So, is there a way to make texmacs NOT to change math strings into
upright (other than known  math functions)?
