rep_specialchars_output() function may destroy UTF8 encoded text

[Neck]

in rep_specialchars_output()

the following code applies:

// convert nbsps back to normal spaces if not html
if ($enctype!='html')
  $str = str_replace(chr(160), ' ', $str);

This might break UTF8 encoding since chr() return the correponding char in PHP's core's encoding which is iso. At least it was breaking all ajax answer on my server.

I corrected that part with:

// convert nbsps back to normal spaces if not html
if ($enctype!='html') {
  $nbsp = rcube_charset_convert(chr(160), 'ISO-8859-1', $OUTPUT->get_charset());
  $str = str_replace($nbsp, ' ', $str);
}

Hope this help.

NB: it wouldnt work with php6 since core's encoding has been changed to UTF8.

This is already fixed. Dupe of #1484429
