I have reproduced this in a newly created cowbuilder (in fact both multibyte and unibyte tests failed), and tested that setting LC_ALL to C.UTF-8 indeed fixes this issue. After a failed attempt to use "setenv" in the test fixture in wgrep-test, I resorted to override elpa test to set LC_ALL which worked for my cowbuilder. The new changes are now pushed to team repo and a new package is dput to mentors. PTAL, TIA! -- Xiyue Deng
