ASP CODEPAGE 65001和Mysql 5 utf-8

Question

charset = UTF-8

CODEPAGE = 65001

MySql version: 5.0.92-enterprise-gpl-log

ADO.Version = 2.8

When I performe a search with unicode characters, like this:

INSERT INTO table (utf8) VALUE ('♂')
SELECT utf8 FROM table WHERE utf8 = '♂' // \u2642

Where utf8 is VARCHAR collation utf8_unicode_ci

MySql return 0 rows.

Removing CODEPAGE=65001 MySql return 1 row. BUT Server.HTMLEncode now return weird symbols and utf8 characters now have length > 1. Not a big deal.

edit:

Ok, now I'm confused: this query works:

SELECT utf8 FROM table WHERE CONVERT(utf8 USING latin1) COLLATE latin1_general_ci = '♂'

obviously this is bad, it ignore INDEXs.

Any help?

Do not include string literals in ASP script that have characters outside of the ASCII range. The script engine parser doesn't do multi-byte character sets. Use ChrW with the Unicode value for other characters.
