Allow character variants in username I am trying to import some users from a phpBB forum and found an odd thing: in phpBB I have some users with weird characters in the username. Eg: Henriëtte . 

The problem is that in Drupal I can't create 2 users with the username "Henriëtte" and "henriette". Apparently "Henriëtte" = "henriette" and this will give an warning saying that the username already exists.

Is there any way to import both usernames in Drupal? Thanks.

[LATER EDIT]

The database encoding is utf8_general_ci. Also, after further investigation the user_load_by_name() function is responsible for returning a valid user even if one letter is different (ë > e). Also, user_load_by_name will in the end use entity_load() to load the user object.
Found the answer. 

The encoding should be utf8_bin not utf8_general_ci
