So far I have been unable to find any documentation that implies this.
The best I have found is from the setlocale man page at, which
          Represents the character set in use for the internal
          representation of text.

It is hard for me to infer from the above that codeset also specifies
the character set of the terminal.  On the other hand, the
solaris-specific documentation at
indicates that if the terminal does not support UTF-8, then one can
use the appropriate streams kernel module to perform the UTF-8 to
whatever conversion.

At the moment, all I plan to support in the initial versions of slang
2 is UTF-8, or no assumed character set.  In the latter case, a
character will be represented as a byte, much in the same way as
version 1.x of the library does now.  I think that it is too much to
expect the library to portably perform, e.g., koi8 to UTF-8
conversions on the fly.  The way I intend to handle this with jed is
that jed will perform the character set conversions to and from its
internal UTF-8 representation when files are read from or written to
the disk.
