Solution 1 :

As @RABI said, to encode reserved characters (such as #) into url content, you should use the correct url encoding.

The following page contains an ASCII url encoding table:

Notice that if you want to programmatically encode strings you can use in js the function encodeURIComponent(string).

Solution 2 :

There are special characters which are reserved and not to be used as a part of a url.

The characters which may be used in a url are:


Note it does not say where in the url they are to be used. Any other character needs to be encoded with the percent-encoding (%hh). Each part of the URI has further restrictions about what characters need to be represented by an percent-encoded word.

Note that some of these characters for example, the hash symbol, have specific meanings, and if you want to avoid these “meanings” then you must use the percent-encoding. The way to use this programatically is by using the built-in function:

const my_hash_symbol = encodeURIComponent("#");
console.log(my_hash_symbol); // => %23

// Later, decode it if you wish
const original_symbol = decodeURIComponent("%23");
console.log(original_symbol); // => #

Edit: The “meaning” of the hash-symbol (“#”) results in the browser looking for a file named KM_72 instead of the full KM_72#050#500.svg, which of course does not exist.

The ‘#’ character falls into the category of “delims”:

delims = "<" | ">" | "#" | "%" | <">

which does not cause a crash or error (directly), but does change the behaviour of the browser’s file searching mechanism which results in a non-direct 404 error.

Problem :

I have a lot of images with a url like this one:


When I will open the image in my Laravel application, the server response is 404.

If I change the file name to KM_72-050-500.svg it works. It means, that the path is ok.

The images are from a customer. So, I like to use themes with the original name.

Is there a possibility to change the url to cover the #?

Try replacing # with %23 which is url encoded text for #
