On Android 5.0.1, Gforth does not display non-ASCII characters, no difference from the keyboard or from a source file (UTF-8 or ISO 8859-1 encoded): non-ASCII characters are displayed as a reverse-video question mark or omitted. I tried it also on a recent version of Android, same problem.
Is it a Gforth's issue, or maybe additional system fonts are needed? -- Marcos Cruz http://programandala.net
