Hi meta!

I've just tried to "Share This" feature from http://area51.stackexchange.com/proposals/16870/le-bon-usage-du-francais-french-usage then selected Twitter.

It ends up at this address : http://twitter.com/?status=Stack%20Exchange%20QnA%20site%20proposal%3A%20Le%20bon%20usage%20du%20fran%EF%BF%BDais%20[French%20usage]%20http%3A%2F%2Fbit.ly%2Fi9nlSu with the message : Stack Exchange QnA site proposal: Le bon usage du fran�ais [French usage] http://bit.ly/i9nlSu

So there is a little problem with UTF-8 I guess, since the character should be ç which is not in ASCII set.

With mail I've got : Stack Exchange Q&A site proposal: Le bon usage du franXais [French usage] with a square instead of X.

It's ok for facebook.

It fails on LinkedIn with We’re sorry. Something unexpected happened and your request could not be completed. Please close this window and try again.

I did not tried the rest of social networks.


The problem seems to originate from the area51 page at first. The links uses fran%E7ais instead of fran%C3%A7ais.

What is the function used to do this? Seems that the source charset is wrong here.


This is fixed now. Thanks for the report.


The ç is actually Unicode U+00E7, or UTF-8 C3 A7. Instead, in the URL one gets EF BF BD, which is UTF-8 for Unicode U+FFFD:

used to replace an incoming character whose value is unknown or unrepresentable in Unicode

So, displaying � is actually correct. And I guess one would see the very same sequence for any other non-ASCII character? Some erroneous double encoding that rightfully fails, maybe?

Using C3 A7 works fine though, for Twitter:
