| * Note: Turning off all of convtest.cpp if !UCONFIG_NO_LEGACY_CONVERSION |
| * is slightly unnecessary - it removes tests for Unicode charsets |
| * like UTF-8 that should work. |
| * However, there is no easy way for the test to detect whether a test case |
| * is for a Unicode charset, so it would be difficult to only exclude those. |
| * Also, regular testing of ICU is done with all modules on, therefore |
| * not testing conversion for a custom configuration like this should be ok. |
