+Description: Set LANG to hopefully make D07multibyte.ztst pass
+
+It failed on the buildds as well as on Salsa runners, but neither
+locally not in pbuilder. Upstream suspects that LANG needs to be set
+(correctly) to pass.
+
+Original comment by Jun:
+
+I've found that the test Xpassed if LANG was unset:
+
+% unset LANG
+% make TESTNUM=D07 check
+./D07multibyte.ztst: test XPassed.
+
+It seems we need to export LANG (in ztst.zsh) to pass it to
+$ZTST_testdir/../Src/zsh.
