W3C validator error with Google Font link


I've just begun my first Treehouse Track and run into my first snag.

W3c is saying that the Google Font Standard Code is incorrect even though it was pasted directly from http://google.com/fonts.

Here is the line in error:

<link href='http://fonts.googleapis.com/css?family=Changa+One|Open+Sans:400italic,700italic,400,700,800' rel='stylesheet' type='text/css'>

Here is the error from W3C validator:

Error Line 7, Column 142: Bad value http://fonts.googleapis.com/css?family=Changa+One|Open+Sans:400italic,700italic,400,700,800 for attribute href on element link: Illegal character in query: not a URL code point.
…ne|Open+Sans:400italic,700italic,400,700,800' rel='stylesheet' type='text/css'>

My understanding of the error is that this is incorrect:


I can see in the tutorial video that Nick's HTML was validated just fine, while mine triggered this error. Is this something new with Google.com/fonts, or am I just missing something?

Thanks for the help!

Hi Bryan,

You have to url encode the vertical bar |. Replace it with %7C

Thanks, Jason.

Strange that Google chose to use the vertical bar instead of the url encoded version. This is more of a rhetorical question, but is this a case of W3C saying that it should be a certain way and Google preferring another way?

You're welcome.

This stackoverflow answer has some information about it.

Seems as if google made a bad choice to use that character.

Also, it seems that you probably don't have to fix it but you should if you'd like to conform to the standards.

Not sure why google continues to not encode the character but at least it's an easy fix.

Thanks again, Jason. It's also a good reminder that I can just Google (search) an error (or parts of it) to find helpful info. I see that I'm not at all alone in this one, especially on Treehouse.

Yeah, I think when I searched to find that stackoverflow link again there were 3 or 4 results from this forum. It's coming up regularly in the forums here so no you're not alone.

I feel that it should just be put in the teacher's notes. It mentions that you might get an error but now how to fix it.

Good point. And it sounds like I should also start reading the teacher's notes.
