22 /* We handle three different modes here.
24 Capable systems have the full suite: wchar_t support and iconv
25 (perhaps via GNU libiconv). On these machines, full functionality
28 DJGPP is known to have libiconv but not wchar_t support. On
29 systems like this, we use the narrow character functions. The full
30 functionality is available to the user, but many characters (those
31 outside the narrow range) will be displayed as escapes.
33 Finally, some systems do not have iconv. Here we provide a phony
34 iconv which only handles a single character set, and we provide
35 wrappers for the wchar_t functionality we use. */
