URL Encoding for C#, F#, and Other Language with Special Characters

[wmboyles]

When one tries to go toGET /language/C#, they very reasonably get sent to results for the C programming language. This is because the hash in URL encoding is a segment identifier. If one instead correctly encodes the hash (or sharp), going to GET /language/C%23, they are correctly given results for the C# programming language. However, for the same encoding reason I described above, the results will show 404's.

For example, consider one of the URLs returned by the API,

https://raw.githubusercontent.com/cat-milk/Anime-Girls-Holding-Programming-Books/master/C#/Chisaki_Tapris_C#.png

Using this link directly will result in a 404. However, if one changes the #'s to their expected URL encoding,

https://raw.githubusercontent.com/cat-milk/Anime-Girls-Holding-Programming-Books/master/C%23/Chisaki_Tapris_C%23.png

The image is found. This change would enable the senpy.club page for C# to actually show images.

Note the same problem is present for F#. A similar issue is also present for C++. However, it is more subtle because most of the images load correctly. However, when one clicks on a certain image, they are instead redirected to an image for the C language.
