File name for non-English users

[murinp]

The final file name is strange for non-English user name.

E.g. user "Karolína Mílová" generates file names "karolana-malova_avatar.jpg" rather than "karolina-milova_avatar.jpg".

Wouldn't be better to use something like $user->user_nicename which is already URL sanitized instead of $user->display_name in unique_filename_callback function?

Line 538 in 606d8a6

$name = $base_name = sanitize_file_name( strtolower( $user->display_name ) . '_avatar' );
