It seemed like this should be a long resolved issue, but after a lot of searching I can't get it working. Hopefully, it's just a configuration problem.
I'm running an old DOS office suite under dosemu in Ubuntu 14.04. Everything seems to work fine except that I can't manage to print the line-drawing characters which form part of the cp437 character set characteristic of DOS.
I am able to to print to my USB printer and also to the cups-pdf printer, but in both cases these special characters appear as others with accents and umlauts, obviously from a different character set. The same problem occurs, in fact, from the DOS EDIT program.
In the dosemu configuration file, .dosemurc which I copied to my home directory, I set the following:
$_external_char_set = "utf8"
$_internal_char_set = "cp437"
Unless I'm mistaken, the unicode character conversions is not being performed correctly. Does anyone have any ideas how I can fix my character set problems?
