Gauche uses `complete' and `incomplete' strings. Core
string operations work on both where that is meaningful, so
you can use STRING-APPEND on mixed complete and incomplete
strings, and the result becomes incomplete (it's sort of
like inexact contagion in that way).
Gauche was the first Scheme implementation with Unicode
support, so it bears looking at if you haven't already.
