## Summary of Changes
Hello @Arunodoy18, I'm Gemini Code Assist[^1]! I'm currently reviewing this
pull request and will post my feedback shortly. In the meantime, here's a
summary to help you and other reviewers quickly get up to speed!
This pull request enhances the Apache Beam SDK's `FileSystems` utility by
adding robust support for handling file paths that contain characters typically
interpreted as glob wildcards. By providing explicit methods to escape and
unescape these characters, the change ensures that users can specify file names
with literal `*`, `?`, `{`, and `}` without them being mistakenly treated as
pattern-matching wildcards, thereby improving the accuracy and flexibility of
file system interactions within Beam.
### Highlights
* **New Glob Wildcard Escaping Utilities**: Introduced
`escapeGlobWildcards(String spec)` and `unescapeGlobWildcards(String spec)`
methods to `FileSystems` to handle literal glob metacharacters (*, ?, {, }) in
file path specifications.
* **Addresses BEAM-13231**: This change resolves the issue where files with
literal glob metacharacters in their names could not be correctly matched by
treating them as wildcards.
* **Comprehensive Testing**: Added extensive test cases for both new
methods, including scenarios for escaping, unescaping, and round-trip
verification to ensure correctness.
