[antlr-interest] How to disable error messages

[JLIST]

Hi,

I'm using Python code generated by Antlr. I'm getting a lot
of errors like this:

line 1:0 no viable alternative at character '\xe6'

The grammar works OK so I'd like to disable these errors from
the console after starting the program. I wonder if there is a
simple way to turn that off from code?

Thanks,
Jack
