+Special characters in query params must be properly URL-encoded to work correctly. Common characters that need encoding:

+- `:` → `%3A`
+- `/` → `%2F`
+- `?` → `%3F`
+- `#` → `%23`
+- `&` → `%26`
+- `=` → `%3D`
+- `+` → `%2B`
+- Space → `%20` (or `+`)
+
+Example with special characters:
+```ts
+Original: `Write a function: def hello()`
+Encoded: `/c/new?prompt=Write%20a%20function%3A%20def%20hello()`
+```
+
+You can use JavaScript's built-in `encodeURIComponent()` function to properly encode prompts:
+```javascript
+const prompt = "Write a function: def hello()";
+const encodedPrompt = encodeURIComponent(prompt);
+const url = `/c/new?prompt=${encodedPrompt}`;
+console.log(url);
+```
+
+Try running the code in your browser console to see the encoded URL (browser shortcut: `Ctrl+Shift+I`).
