Extended ASCII? There are many extended ASCIIs I guess, and the Model T family has its own.
HTERM was designed to do the mapping from UTF-8 to/from model T, on its own, which makes it function well with Linux (it also discards handles/discards some xterm escapes). The built in terminal will display whatever codes are sent to it. If you're interested, the community determined a mapping you could start with if assuming your base is unicode. https://bitchin100.com/wiki/index.php?title=Unicode_Mappings -- John.
