[Gambas-user] non printable char "Ⱶ" how to remove from string!!!!!

[Fabien Bodard]

To resume ... in the old past of ascii all standart printer or monitor
can manage ascii and print 32 to 127 chars. So Ansi C provide a
standart function named IsPrint that allow to say if a char was able
to be printed.

IN 2015... Ascii is known in it's 8 bit format so printable chars are
from 32 to 255.

Characters lower than 32 are for monitor, modem and printer management.

Thanks to my terminal studie i'm now able to understand all of that :-).

It's really interresting to study the past ...
