Developers often struggle with Unicode text processing errors, especially when handling special characters or encoding issues. This leads to bugs and user experience problems in internationalized applications.
You’d build a lightweight library or CLI tool that detects, explains, and fixes common Unicode issues like incorrect encoding, character escapes, or normalization problems.
Paid customers would be SaaS companies and developers building global apps, who need reliable text handling to avoid user complaints.
The MVP could be a simple command-line tool that identifies Unicode errors in a text file and suggests fixes.
The biggest risk is competition from existing Unicode libraries, so focus on ease of use and clear error explanations.
