* 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.
