Looks like a problem in NoViableAltForCharException.java. It's printing a
wrong value because it's geared to byte sized values (probably my mistake
when trying to fix printing illegible errors)

If the value of that delta is in that character range it should be ok I
guess.

I'll see if I can fix the thing for 2.7.4 release.

Cheers,

Ric
