[plt-scheme] scheme_eval_string

Hi all,

In v299, The document of scheme_eval_string is the same as that in v209.

Scheme_Object *scheme_eval_string(char *str, Scheme_Env *env) 
Reads an S-expression from str and evaluates it in the given namespace (raising an exception if the expression returns multiple values).

Does this mean that str is a nul-terminated byte string that is a UTF-8 encoding? If yes, should better be explicitly mentioned in the
document.
