What types does the function expect and return?

Unfortunately, the code index for this repository has minimal coverage and didn't return the type information. However, based on the README excerpt, I can tell you what the function expects and returns from the usage example:

From the README example [shown in the Usage section]:

• Input: A string (e.g., 'How much $ for a 🦄?')
• Output: A string with RegExp special characters escaped (e.g., 'How much \\$ for a 🦄\\?')

The function is a default export called escapeStringRegexp that takes a string parameter and returns an escaped string safe for use in a RegExp.

To see the exact TypeScript type signatures, you would need to examine the main source file directly. The repository uses both JavaScript and TypeScript, so the types are likely defined in a .d.ts file or inline in the source. I'd recommend looking at the entry point file (likely index.js or index.ts in the root or src/ directory) to see the precise type annotations.

• Does the function handle Unicode characters specially?
• Can the escaped string be used anywhere in a regex?
