I'm not an authority on that. R5RS requires only the ASCII
character repertoire; various Schemes have supported Unicode
in various ways and to various degrees.
It's been a vexed question whether R5RS and earlier RnRS documents
imply that strings must provide O(1) random access to the characters
that constitute them. It is not so in R6RS.
