One would expect the following sequence of forms to set sppos to 6:

(set! jstr (make <java.lang.String> "DOMAIN Some Name"))

(set! sppos (invoke jstr 'indexOf #\space))

but, as written, it fails to find a matching character.

However, replacing #\space by 32 works, correctly returning 6.

It should be fairly easy to work around since char->integer will convert a Scheme character into an integer and a trivial macro or function such as:

(define-syntax javachar
(syntax-rules ()
((javachar schemechar)
(char->integer schemechar))))

ought to provide reasonable syntactic sugar.
