/* We handle three different modes here.
|
| 23 |
|
|
|
| 24 |
|
|
Capable systems have the full suite: wchar_t support and iconv
|
| 25 |
|
|
(perhaps via GNU libiconv). On these machines, full functionality
|
| 26 |
|
|
is available.
|
| 27 |
|
|
|
| 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.
|
| 32 |
|
|
|
| 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. */
