 **Note** that you must encode the parameters containing [reserved characters](https://www.rfc-editor.org/rfc/rfc3986#section-2.2).
 
-If your routes' parameters are not Basic Latin charaters, you may face a performance drop. To avoid it, you can customize the way the parameters are parsed by passing a custom decoding function. Read more about it [here](https://github.com/delvedor/find-my-way/pull/211).
-The parsing function is called when the request URL contains one or more encoded special characters: `# $ & + , / : ; = ? @`.
-
-```js
-const router = require('find-my-way')({
-  decodeUriParameters: (stringToDecode) => {
-    // called when the request URL contains st least one special character: `# $ & + , / : ; = ? @`
-    return decodeURIComponent(stringToDecode)
-  }
-})
-```
-
-By default, this module relies on [fast-decode-uri-component`](https://www.npmjs.com/package/fast-decode-uri-component) to parse the encoded path parameters.
