My server:
mysql> show charset like 'utf16le';
+---------+------------------+--------------------+--------+
| Charset | Description | Default collation | Maxlen |
+---------+------------------+--------------------+--------+
| utf16le | UTF-16LE Unicode | utf16le_general_ci | 4 |
+---------+------------------+--------------------+--------+
1 row in set (0.00 sec)
mysql> show collation like 'utf16le%';
+--------------------+---------+----+---------+----------+---------+
| Collation | Charset | Id | Default | Compiled | Sortlen |
+--------------------+---------+----+---------+----------+---------+
| utf16le_general_ci | utf16le | 56 | Yes | Yes | 1 |
| utf16le_bin | utf16le | 62 | | Yes | 1 |
+--------------------+---------+----+---------+----------+---------+
2 rows in set (0.00 sec)
How to repeat:
via c/net, run this query against a mysql server that supports the charset:
select _utf16le "aaaaaaaa"
Suggested fix:
add the mapping to function: private static void LoadCharsetMap() ?
don't hardcode charsets?
