Does anyone have a link to a definition of universal alpha as used in the DMD docs?

Here's something:  http://www.algonet.se/~afb/d/universalalphas/

http://www.open-std.org/JTC1/SC22/WG14/www/docs/n1124.pdf

Look for Annex D...

"Universal alphas are as defined in ISO/IEC 9899:1999(E) Appendix D."

Thanks, I'll take a look.

BTW: after googleing for ["universal alpha" UTF] and filtering out the false+s *everything* left was referencing D. Now what does that say?

In article <op.tackd4egpo9bzi@moe>, Chris Miller says...

Ha ha, another pointer to a D-reference

While searching for the reference for this, I came across this interesting article of floating point arithmetic.

As it says in the text file, the list was from "ISO/IEC 9899:1999 (E)"
http://www.algonet.se/~afb/d/universalalphas/universalalphas.txt

http://www.open-std.org/JTC1/SC22/WG14/www/docs/n1124.pdf
"Annex D (normative) - Universal character names for identifiers"
1. This clause lists the hexadecimal code values that are valid in
   universal character names in identifiers."

Then I took that list, and generated a D program to print all of them:
