Subject: [PATCH] GPT strings are UCS-2LE not UTF-16
There was a problem using UTF-16, it was writing the Byte Order Mark
before the string which caused problems with older versions of parted
reading the partition name. The test was skipping these 2 bytes when
checking the written string.
* libparted/labels/gpt.c: Switch to UCS-2LE for GPT Partition names
* tests/t0251-gpt-unicode.sh: Update the test
