I've read What is the _snowman param in Ruby on Rails 3 forms for? and it says, that rails utf8 checkmark (former snowman) hack is only needed for Internet Explorer.
But I can't find a list, WHICH Internet Explorers require the hack. So it would be good to know, which versions are affected.
The background is, that
- it looks ugly
- it confuse users
- (it seems) some google tools have problems with that (try https://testmysite.withgoogle.com and put in
https://www.google.com?utf8=✓
, it loads forever and aborts after ~5-10 min withYour site took too long to analyse
)
