How to fix Internet Explorer and Firefox form encoding issues when posting data to a server having a different encoding
This snippet explains how to fix Internet Explorer and Firefox form encoding issues when posting data to a server having a different encoding than the source system.
This happens, for example, when you host a form on a server using ISO-8859-1 that posts data to a server using UTF-8.
The fix for Firefox (and Opera and other sensible browsers) is to use the accept-charset attribute:
<form ... accept-charset="utf-8">
The fix for Internet Explorer is to use a hack:
<form ... accept-charset="utf-8">
<input type="hidden" name="enc" value="™">
</form>
The hidden input field will make Internet Explorer understand that you want it to support UTF-8.
