By default, older versions of IE (<=8) will submit form data in Latin-1 encoding if possible. By including a character that can't be expressed in Latin-1, IE is forced to use UTF-8 encoding for its form submissions, which simplifies various backend processes, for example database persistence.
If the parameter was instead utf8=true then this wouldn't trigger the UTF-8 encoding in these browsers. http://programmers.stackexchange.com/questions/168751/is-the-use-of-utf8-preferable-to-utf8-true |
