antlrworks2 can not open grammar files with utf-8 encoding?

[mdakin]

I am trying to open a antlr4 lexer grammar file with some Turkish characters in it, something like this:

// Letters

fragment TurkishLetters

    : [a-zâîûçğıöşü];

fragment TurkishLettersCapital

    : [A-ZÂÎÛÇĞİÖŞÜ];

When I try to open it with antlrworks2 it gives me this error message:

The file <snip>/TurkishLexer.g4 cannot be safely opened with encoding US-ASCII. Do you want to continue opening it? Yes/cancel

If I open it, it garbles the Turkish characters and I could not find an option to select a default encoding, do I have to use ascii only for defining grammars with \u escaping for non ascii characters?

Thanks.

Have you tried saving your grammar in UTF-8 with the byte order mark? The byte order mark is the only reliable way of auto-detecting the encoding of a file, and since NetBeans doesn’t expose an “Open with Encoding” option I’m not sure how the encoding is set otherwise.

 

Thank you,

Added a BOM header as well but did not work. Maybe it is failing because my locale is tr_TR.UTF-8 anyway we are back to \u escape codes. (Btw, IMHO, the default encoding should always be UTF-8 for the antlrworks)
