missing arrow glyphs in 1.10

Hi,
Lots of terminals (particularly non-Windows) were being screwed up by 8086tiny outputting the "non-printable" ASCII characters under 32 decimal. As a result, in 1.10 any characters below 32 are replaced with a space. This is why the arrows are no longer there, on Windows. (They never showed correctly on non-Windows platforms.)

I'll have a think about solutions to this problem that don't sacrifice the arrows on Windows.

SETEDIT translates arrows to <(◄[17],←[27]) >(►[16],→[26]) ^(↑[24],▲[30]) v(↓[25],▼[31]) and others to "*", what do you think?

and another idea is to tell BIOS from 8086tiny weather host is windows or not, for to or not to translate control characters:

roytam1,
8086tiny 1.15 should be released today, and will include a translation from the non-printable arrow characters to printable characters, along the lines of how you describe, except that instead of using a long CMP chain I use a single table and XLAT. I think this will do what you are looking for.
