some changes of my own

[ruilong]

I wanted to change the import csv file from utf-8 only to handle some standard excel exported files, so I changed the line

bq. $tables[intval($nb_c / MAX_COLUMNS)][$nb_l][$nb_c] = $column;

in AdminImport.php to the following

bq. $tables[intval($nb_c / MAX_COLUMNS)][$nb_l][$nb_c] = utf8_encode($column);

and now it works for me, swedish characters show up correctly. BUT to make this usable by all people, I wanted it to NOT encode the string to utf-8 if it already was utf-8, that way my code would be easy to just copy-paste by the PS team and voíla or croussant the import function would be improved for everyone and I would have made a small contribution

So I set to the task and figured this should work

bq. if(mb_detect_encoding($column,'UTF-8')){$tables[intval($nb_c / MAX_COLUMNS)][$nb_l][$nb_c] = $column;}
else{$tables[intval($nb_c / MAX_COLUMNS)][$nb_l][$nb_c] = utf8_encode($column);}

but it dosn't I just get nothing displayed at all.. I think it has something todo with the mb_detect_encoding function, but I'm not the best php developer, .net is more my strong side so maybe I made some n00b misstake here

any inputs on how this could be fixed?
or maybe if someone can tell me how to get error reports during development, that would help also
