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