Question

I’m trying to generate characters in different encodings using MySQL.

My script looks like this:

SET @id := 678;
SELECT
    @id,
    CHAR(@id USING utf32),
    CHAR(@id USING utf16),
    CHAR(@id USING utf8),
    HEX(CHAR(@id USING utf32)),
    HEX(CHAR(@id USING utf16)),
    HEX(CHAR(@id USING utf8))

My expected result is:

678
ʦ
ʦ
ʦ
000002A6
02A6
CAA6

What i actually get:

678
ʦ
ʦ
            <-- Questionable
000002A6
02A6
02          <-- Questionable

Is there a way to do this in MySQL?

Thanks at lanzz.

SET @id = 45678;
SELECT
    @id,
    CHAR(@id USING utf32),
    CONVERT(CHAR(@id USING utf32) USING utf16),
    CONVERT(CHAR(@id USING utf32) USING utf8),
    HEX(CHAR(@id USING utf32)),
    HEX(CONVERT(CHAR(@id USING utf32) USING utf16)),
    HEX(CONVERT(CHAR(@id USING utf32) USING utf8));

Result:

45678
뉮
뉮
뉮
0000B26E
B26E
EB89AE

Try CONVERT(CHAR(678 USING UTF16) USING UTF8). The CHAR() call will convert your unicode character code into an actual string, and CONVERT() will convert that string into actual UTF8.
