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

Fri Jan 22 15:37:46 CET 2016

now i tested fully the hardware, the char non-printable and not definitive
in the extended ASCII table that i got *was a garbage*.. my parner must
made a complete function to remove it .. i talk at the manufacturer but
there's no response..

seems like that any guindow-like made hardware are fully of defects!
