Subject: lib-charset: Added UTF-7 state checking unit test.
X-Git-Tag: 2.2.20~17
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8a0ef83121a9ae375448efb2e1f08e136bf04e22;p=thirdparty%2Fdovecot%2Fcore.git

lib-charset: Added UTF-7 state checking unit test.
This was an idea of a way to test for a bug in FreeBSD iconv(), but nobody
reported if it did anything. So lets add it here and see.
