Seems \v is not available in java (after quick check of the spec) In C/C++
it's valid. Not 100% sure if '\\v' will work might (my guess is no) try
'\013' in stead which should be equivalent to \v.

I added \v to the action lexer of C++ mode, where it will make sense.
(meaning that in the next release it's possible to use '\v' in actions)

Cheers,

Ric
