Jun 04, 2013 · If I'm reading this right, ANTLR does not currently support 32-bit characters in the lexer definition.

If so, is there plans to support entering arbitrary Unicode in lexer definitions?

Scanning Unicode Characters. ANTLR (as of 2.7.1) allows you to recognize input composed of Unicode characters; that is, you are not restricted to 8 bit ASCII characters. I would like to emphasize that ANTLR allows, but does yet not support Unicode as there is more work to be done. For example, end-of-file is currently incorrectly specified:

So far I’ve been an enthusiastic user of ANTLR3, mostly for the MySQL Workbench product, where I based all the parsing infrastructure on the ANTLR3 C runtime. However, with the appearence of v4 a few years ago this ANTLR version got outdated and the support for it decreased constantly since then.
