string - construct a string from the supplied characters

(import (rnrs))                     ;R6RS
(import (rnrs base))                ;R6RS

(import (scheme base))              ;R7RS

(string char ...)

Returns a newly allocated string composed of the arguments.

Some implementations have a single empty string object. See make-string(3scm).

Returns a single value; a string.

(string #\Q #\u #\u #\x)  =>  "Quux"

This procedure is mostly used when building quite small strings. It's one way to convert a character to a string.

This procedure works the same since R4RS, notwithstanding the limits on strings that an implementation may have.

This procedure can raise exceptions with the following condition types:

&assertion (R6RS)

An argument was not a character.

R7RS

The assertions described above are errors. Implementations may signal an error, extend the procedure's domain of definition to include such arguments, or fail catastrophically.

Unsupported characters (R7RS)

It is an error to pass this procedure a character which the implementation does not support. 7-bit ASCII (except #\null) must be supported. Any other character is optional and potentially an error (as described above). You can use the full-unicode feature identifier in cond-expand(3scm) to check if all of Unicode 6.0 is supported.
