The infinity (∞) symbol gets converted to ∞ when it is inserted into my MySQL table by a PHP script, but if I insert it directly from phpMyAdmin, it inserts correctly. The symbol is passed to the PHP script by a GET call with the JavaScript function encodeURIComponent() around the contents. The field in the MySQL database is utf8_swedish_cl. How do I get ∞ to insert as ∞ into the database?

  • I know this has not much to do with the answer but just to point out, when you retrieve the data, it will be in the correct format/correctly encoded. I guess it's just the way MySQL likes to represent non-ASCII characters. – Waleed Amjad Jan 15 '10 at 01:06

Check this real good SO answer: UTF-8 all the way through…

Are you sure that phpMyAdmin is doing it right? ∞ Looks a lot like a UTF8 character stored in a latin-1 column.

What do you get when you do this select hex(column_name) from the_table?

  • If it's E2889E, then your connection is UTF8, your column may not be.

  • If it's C3AC, then your connection is latin-1 and your column is utf8.

  • If it's EC, then both your connection and column are latin-1

Here's a quick way to verify that the column's encoding is UTF8: 

select 
    column_name, character_set_name, collation_name 
from 
    information_schema.columns
where
    table_name = '_your table_'

Are you setting SET NAMES utf8 before inserting the content into the database?

  • That does work to insert it correctly, though it still displays incorrectly. I'm going to use Alix Axel's answer from the link to get everything UTF-8 all the way through. – James Simpson Jan 15 '10 at 01:32

Don't forget the "query" SET CHARACTER SET utf8 at the beginning of your scripts.
