-Special characters in the prompt 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:
-```
-Original: Write a function: def hello()
-Encoded URL: /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}`;
-```
-
