Unicode Madness

OK, I have been trying to make additions to eqn so that the .eqn context give you as much power as TeX -- without the backslashes and other finger gymnastics. Alas, I have run up against the the true nightmare that is math symbols in this modern age.

When I found a script on StackOverflow to list all the symbols supported by XeTex, I got a 50+K file!

So I backed off a bit and simply added the ability for users to use Unicode escapes to define the symbols they want to use. Something like

.eqn
define integralAbomination "\[u2A1A]"

integralAbomination x dx = inf
..eqn

To get

Spacing

The other problem I found is that in MathML mode, all the Greek letters got treated as operators, with attendant extra space. I think I have this fixed, but now some actual operators are now acting like variables... Note the lack of space around the equal sign.

Anyway, power mathematicians can define their own symbols using the Unicode code points as above, but I cannot say that I'm finished yet...

Thanks for the heads up.

For the nonce, try logging out and logging back in. Please let me know if that works. (Would narrow down my search.)

Logging out and back in cleared previously viewed notifications, including notification of new subscribers I failed to mention as well.

Thanks, Carl. It's been working fine.
