There is a known bug (in the sense that I reported it some time ago)
that causes GNU readline and hence Bash trouble on Sparc/Solaris with
character codes >=128. This is because by default Sparc/Solaris uses
signed characters. Thus I am currently using a version of bash and
readline compiled with the gcc option which forces unsigned characters.
I don't know if this has anything to do with the above problem . . .
