Comparison table seems to have invalid characters

[tiesont]

Viewing the Charting Library Comparison section (http://www.chartjs.org/docs/#notes-charting-library-comparison), I assume there should be something like a checkmark, but this is what I see:

Using Windows 10, I see the same thing in Firefox, Chrome, and Edge, so I don't think it's a browser issue.

Thanks for reporting this @tiesont

This is reproducing on my MBP in Chrome as well
@zachpanz88 thoughts?

The problem is that the site will only render ASCII and not utf-8 characters (I assume, it depends on how the script @nnnick uses to generate the site works). There should be check marks there as shown in the markdown file. The check mark will have to be replaced with something different, such as an "X" or "Yes".

[tiesont]

Would probably be a simple matter of replacing the character with an entity:

✓ ✓
✓ ✓
✓ ✓
✓ ✓

are all options.

If the documentation site includes the charset meta element:

<meta charset="utf-8" />

the ticks render correctly, so perhaps that is a quicker fix.

[panzarino]

That would probably work, I would like to verify with @nnnick before merging anything, but feel free to submit a PR with the fix.

@zachpanz88 Sorry, just edited my comment. I saved a local copy of the page and swapped out

<meta http-equiv="content-type" content="text/html; charset=windows-1252">

with

<meta charset="utf-8" />

and the Unicode characters show up, so I assume the meta tag is just wrong (I don't know what charset windows-1252 is - I assume ASCII or UTF-7).

Swapped the characters in #3444 - should be good-to-go?

[etimberg]

Fixed in #3444
