I have a problem with special characters in my database. They now display correct, but sql seems to ignore them in queries. For example, unfortunately I have these entries:

Morgait
Morgaít
Mórgait

Now these names had a UNIQUE key, and while trying to add the second and third after the first one, it would already break saying that the last 2 couldn’t be added since the name would no longer be unique. In short, í gets treated as a normal i, and ó as a normal o.

When I query:
SELECT * FROM member WHERE charname = 'Morgait'
I get all 3 as result. Same for when I change the i to í, o to ó or even both at the same time.

How can I make the database see these differences? I have the collation of the table set to ascii_general_ci (also tried UTF 8 unicode ci).

    All of those collations are accent insensitive. You can try utf8_bin which is accent sensitive, however it’s also case sensitive.
    With accent insensitive collations, for example é equals e or ë and so on.

    SELECT * FROM member WHERE charname = 'Morgait' COLLATE utf8_bin

    should do the trick. If you need case insensitivity, you can try 

    SELECT * FROM member WHERE LOWER(charname) = LOWER('Morgait') COLLATE utf8_bin
