Notice there is no slash at the end of it. It won't work with the slash at the end.
Maybe a bit more tweaking options, like the basic AA, hinting, etc would help.
What are you rendering on? What options in particular would you like to include? I know that different OSes have different font renders. And probably different programs, too. I'm always glad to make the site better, so I'm open for suggestions.
I find it odd that all options are on windows 7 given that these are PROGRAMMING fonts. In my experience, windows programmers are a very small minority, OS X and GNU/Linux being predominant.
When adding a new font, I like to only render the new one because of the sheer number of screenshots, files and time it takes to redo everything. Currently the site contains 2569 individual images. But I'll look into it later today. Maybe I can fix it. It's distracting right now. Good eye for noticing though :D
I'm sure there are other things that tend to annoy me, that are a matter of taste, but that's the first one that came to mind. Maybe some of them have poor differentiation between apostrophe/single-quote/back-tick?

Which is designed to cover all those tricky cases. Do you still think something is missing?
The reason for not flagging the fonts on those differences is that it's kinda tricky. First it would be a lot of work and increase the complexity of the site. But mainly it's not so clear because some fonts like Monoid and Input actually offer highly customizable options to fine tune for these things like slahed or non-slashed zeros etc
I get that it would be a lot of work, and a pull request would be more welcome than a comment :-)
Maybe an interface where others could tag the fonts, and have some suggested tags (dashed-zero, dotted-zero, plain-zero; el-one (1 and l too similar), pipe-I etc) -- and a way to filter on those?
I'm not sure it would be all that helpful, but it's an idea as the number of fonts grow. I suppose I could even see that work for a bigger project that included non-monospace fonts.

* Oxygen mono
* Fira Code
I'll add the other two later today, thanks!
