String coding across UI Tabs

String coding across UI Tabs

My question refers to a master script with the header containing tabs
  1. <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-15">


and a secondary scirpt which is the content of one of the tabs with the same header

Firefox display option is currently 8859-15


When loading strings from my database I read them in ISO8859-1
       
  1. $sCoding = mb_detect_encoding($enreg['Prenoms'],'UTF-8, ISO-8859-1');

Directly displaying the secondary script (for debug) the display is OK for accented characters
But if I want a good display when displaying the secondary script in UI tabs I must utf8_encode the string

Can I do something to avoid that and have the same behaviour for all of the scripts
