Sure, that works. Except as I read it, they're proposing curly braces, e.g.:

"Use Greek capital letters (\N{GREEK CAPITAL LETTER ALPHA}\N{EN 
DASH}\N{GREEK CAPITAL LETTER OMEGA}) to denote figures."

Since Elisp caters to strings that cross line boundaries, it looks like 
lread.c's read_escape should allow arbitrary nonempty white space in 
places where the official Unicode name contains a single space.
