Unfortunately it doesn't seem to work on Windows.

First any combination of valid lc_messages and non-existent encoding
passes the test  strcmp(gettext(""), "") != 0 .
Second for example the combination of ja(lc_messages) and ISO-8859-1
passes the the test but the test fails after I changed the last_trans
lator part of ja message catalog to contain Japanese kanji characters.
