Hi all,
If one wants to specify exotic Unicode ranges, they go beyond \ufff.
Feature request: allow longer ones, such as \u104a0 (Osmanian digit 0: 𐒠).
This symbol is parsed unproblematically by javac , so you’ll have to
adapt you Java parser as well, Terence! (At least, Eclipse doesn’t
complain, although it doesn’t render it properly.)
Probably, you want
fragment JavaIDDigit
: '\u0030'..'\u0039'
| '\u0660'..'\u0669'
| '\u06f0'..'\u06f9'
| '\u07c0'..'\u07c9'
| '\u0966'..'\u096f'
| '\u09e6'..'\u09ef'
| '\u0a66'..'\u0a6f'
| '\u0ae6'..'\u0aef'
| '\u0b66'..'\u0b6f'
| '\u0be6'..'\u0bef'
| '\u0c66'..'\u0c6f'
| '\u0ce6'..'\u0cef'
| '\u0d66'..'\u0d6f'
| '\u0e50'..'\u0e59'
| '\u0ed0'..'\u0ed9'
| '\u0f20'..'\u0f33'
| '\u1040'..'\u1049'
| '\u1369'..'\u1371'
| '\u17e0'..'\u17e9'
| '\u1810'..'\u1819'
| '\u1946'..'\u194f'
| '\u19d0'..'\u19d9'
| '\u1b50'..'\u1b59'
// | '\u104a0'..'\u104a9' osmanian, ANTLR bug!
// | '\u10a40'..'\u10a43'
// | '\u1d360'..'\u1d371'
;
and I’m leaving out the mathematical digits here, didn’t test them with
javac. Similarly, you’ll have to expand Letter.
