-* created by: Markus W. Scherer
-*
-* Test performance (time & memory) of ucnv_countAvailable(),
-* for a before-and-after comparison of
-* ticket 6441: make ucnv_countAvailable() not fully load converters
-*
-* Run with one optional command-line argument:
-* You can specify the path to the ICU data directory.
-*
-* I built the common (icuuc) library with the following modification,
-* switching between old (pre-ticket-6441) behavior of actually
-* trying to load all converters and new behavior of just doing enough
-* to test availability.
-*
-* Code in the ucnv_bld.c haveAvailableConverterList() function:
-#if 0
- // old pre-ticket-6441 behavior
- ucnv_close(ucnv_createConverter(&tempConverter, converterName, &localStatus));
- if (U_SUCCESS(localStatus)) {
-#else
- // new behavior
- if (ucnv_canCreateConverter(converterName, &localStatus)) {
-#endif
