In UCS-2, every character is represented by a two-byte Unicode
code with the most significant byte first. For example:
LATIN CAPITAL LETTER A has the code
0x0041 and it is stored as a two-byte
sequence: 0x00 0x41. CYRILLIC
SMALL LETTER YERU (Unicode
0x044B) is stored as a two-byte sequence:
0x04 0x4B. For Unicode characters and their
codes, please refer to the
Unicode Home
Page.
In MySQL, the ucs2 character set is a
fixed-length 16-bit encoding for Unicode BMP characters.
