MySQL: Variable 'character_set_client' can't be set to the value of 'utf32'

Hello,

I have been trying to convert my database to UTF32 from UTF8. I have converted the database itself, and have converted all of the tables.

However, I cannot set the connection charset to UTF32. I get the above error when I try:

Variable ‘character_set_client’ can’t be set to the value of ‘utf32’

The same thing happens if I try to set it in the MySQL client with:

set names UTF32

I cannot figure out why this is happening, or how to fix it.

Thanks for any help.
