"Smart pointer" definition macro, deletes objects via the closeFunction.
Definition: localpointer.h:548
ucsdet_enableInputFilter
U_CAPI UBool ucsdet_enableInputFilter(UCharsetDetector *ucsd, UBool filter)
Enable filtering of input text.
ucsdet_getConfidence
U_CAPI int32_t ucsdet_getConfidence(const UCharsetMatch *ucsm, UErrorCode *status)

Close a charset detector.
ucsdet_getDetectableCharsets
U_CAPI UEnumeration * ucsdet_getDetectableCharsets(const UCharsetDetector *ucsd, UErrorCode *status)
