New beta release 1.2.7r2021

[boriel]

I have just noticed that 2 new files have appeared in the directory where the .bas file is:

parser.out
zxbasmpptab.py

Maybe it's related to the problem I had.

Nope, they are *rubbish*. I did include them by accident.
The bug is due to the new preprocessor which do not accept "unknown" characters. This is an easy fix. Fixing...
