|
|
* ucnv_err.h:
|
|
* defines error behaviour functions called by T_UConverter_{from,to}Unicode
|
|
*
|
|
* These Functions, although public, should NEVER be called directly, they should be used as parameters to
|
|
* the T_UConverter_setMissing{Char,Unicode}Action API, to set the behaviour of a converter
|
|
* when it encounters ILLEGAL/UNMAPPED/INVALID sequences.
|
|
*
|
|
* usage example:
|
|
*
|
|
* ...
|
|
* UErrorCode err = U_ZERO_ERROR;
|
|
* UConverter* myConverter = T_UConverter_create("ibm-949", &err);
|
|
*
|
|
* if (U_SUCCESS(err))
|
|
* {
|
|
* T_UConverter_setMissingUnicodeAction(myConverter, (MissingUnicodeAction)UCNV_FROM_U_CALLBACK_STOP, &err);
|
|
* T_UConverter_setMissingCharAction(myConverter, (MissingCharAction)UCNV_TO_U_CALLBACK_SUBSTITUTE, &err);
|
|
* }
|
|
* ...
|
|
*
|
|
* The code above tells "myConverter" to stop when it encounters a ILLEGAL/TRUNCATED/INVALID sequences when it is used to
|
|
* convert from Unicode -> Codepage.
|
|
* and to substitute with a codepage specific substitutions sequence when converting from Codepage -> Unicode
