-The code tries to find a codec in a list of codecs. For this it searches for a given prefix.
-But the prefix is of type char16_t, which means 2 bytes per character instead of 1, as was compared here.
-On big endian this created some false positives, as the order of bytes is different and some characters only
-occupy "the first" byte, having the second null'ed out.
-Noticed because of gtest: MediaMIMETypes.MediaCodecs
