I did try
(set-port-encoding! (current-input-port) "UTF-8")
(set-port-encoding! (current-output-port) "UTF-8")
(string-length "𝅬")
but this
but I confess I'm not sure what input port is involved - the part of
Denemo that offers a Guile interpreter interface uses a GTK widget to
input the Scheme text from the user and passes this as the parameter
"script" to this function:
scm_internal_catch (SCM_BOOL_T, (scm_t_catch_body) scm_c_eval_string,
(void *) script,
(scm_t_catch_handler) standard_handler,
(void *) script);
And I see that there is this during initialization of Denemo:
const char prog[] = "(catch #t (lambda () (setlocale LC_ALL \"\")) (lambda
_(display \"Locale not supported by the C library. Falling back to default
\\\"C\\\" locale.\\n\"(current-error-port))))";
scm_c_eval_string (prog);
results in the message saying it is falling back to the default C locale.
I'm lost!
