• UTF-8 all the way through 15 answers

I have <meta http-equiv="Content-Type" content="text/html;charset=utf-8" /> in the header, but it still shows � instead of µ. I tried adding AddCharset UTF-8 .php to .htaccess, but it didn't help.

EDIT: if I just put symbol µ in the file, it displays correctly. I get � when I try to output it from a database.

Answer 1

If something displays as the � UNICODE REPLACEMENT CHARACTER, that means the document is interpreted in a Unicode encoding (e.g. UTF-8) but the byte sequence at this point is invalid in this encoding.

In other words, your data/file is not UTF-8 encoded. Make sure it's saved as UTF-8, not just declared as such.

If you have problems outputting it from a database, it means the data coming from the database is not UTF-8 encoded. See Handling Unicode Front To Back In A Web App.
