The mbstring PHP extension was not found and you seem to be using a multibyte charset. Without the mbstring extension phpMyAdmin is unable to split strings correctly and it may result in unexpected results.
Scroll down the list of things shown in the phpinfo page and look for the mbstring module. It should say something like this...
Multibyte Support enabled
Japanese support enabled
Simplified chinese support enabled
Traditional chinese support enabled
Korean support enabled
Russian support enabled
Multibyte (japanese) regex support enabled
