 I have been lately working on an extension for library filename
 sanitization and seen this on wp-includes/formatting.php :
 {{{#!php
 <?php
 // Used for locale-specific rules
 $locale = get_locale();
 if ( 'de_DE' == $locale || 'de_DE_formal' == $locale || 'de_CH' == $locale
 || 'de_CH_informal' == $locale ) {
         $chars['Ä'] = 'Ae';
         $chars['ä'] = 'ae';
         $chars['Ö'] = 'Oe';
         $chars['ö'] = 'oe';
         $chars['Ü'] = 'Ue';
         $chars['ü'] = 'ue';
         $chars['ß'] = 'ss';
 } elseif ( 'da_DK' === $locale ) {
         $chars['Æ'] = 'Ae';
         $chars['æ'] = 'ae';
         $chars['Ø'] = 'Oe';
         $chars['ø'] = 'oe';
         $chars['Å'] = 'Aa';
         $chars['å'] = 'aa';
 } elseif ( 'ca' === $locale ) {
         $chars['l·l'] = 'll';
 } elseif ( 'sr_RS' === $locale || 'bs_BA' === $locale ) {
         $chars['Đ'] = 'DJ';
         $chars['đ'] = 'dj';
 }
 }}}
 What is the purpose about applying theses replacements only for certains
 languages ?

 Moreover, why base this on the locale and not the user locale ?
