static VALUE nameprep(VALUE self, VALUE str) { return stringprep_internal(str, "Nameprep"); }
Converts a string in UTF-8 format into canonical form, standardizing such issues as whether a character with an accent is represented as a base character and combining accent or as a single precomposed character.
static VALUE nfkc_normalize(VALUE self, VALUE str) { char *buf; VALUE retv; str = rb_check_convert_type(str, T_STRING, "String", "to_s"); buf = stringprep_utf8_nfkc_normalize(RSTRING_PTR(str), RSTRING_LEN(str)); retv = rb_str_new2(buf); xfree(buf); return retv; }
Prepares a string in UTF-8 format according to the 'Nodeprep' profile.
Raises IDN::Stringprep::StringprepError on failure.
static VALUE nodeprep(VALUE self, VALUE str) { return stringprep_internal(str, "Nodeprep"); }

Raises IDN::Stringprep::StringprepError on failure.
static VALUE resourceprep(VALUE self, VALUE str) { return stringprep_internal(str, "Resourceprep"); }
