Special characters like `?` and spaces need to be encoded. There are many online encoders. An example is [this tool](https://www.urlencoder.io/). Simply enter the value of your parameters and use the encoded one. Some encoding examples: - space → `%20` - `/` → `%2F` - `%` → `%25` The key `myKey` and value `Hello World` need to be encoded like the following: ```uri obsidian://adv-uri?myKey=Hello%20World ```
