i could not found anything in the as3 spec but
you can check the old spec at 7.6 Identifiers.
http://www.mozilla.org/js/language/E262-3.pdf
i saw some of the ecma 4 drafts referencing that chapter.
it says unicode letters and unicode escapes are allowed in identifiers,
but i couldn't find the exact unicode ranges to use.

terence parr used the unicode ranges from the java 1.5 spec here 
http://www.antlr.org/grammar/1152141644268/java.g.
maybe they are similar ?

i am also interested in the code ranges of as2 identifiers but could not 
found much about it.

best regards
