About:
Unac is a C library and command-line utility designed to remove diacritical marks and accents from Unicode strings. It primarily targets ISO-8859-1 character sets to convert accented characters into their base ASCII equivalents. This tool is essential for normalizing text data for search indexing or ASCII-only processing.

Key Features:

C library for integration into applications
Command-line interface for batch processing
Supports ISO-8859-1 character stripping
Handles complex character decompositions

Use Cases:

Normalizing user input for search functionality
Converting text for legacy ASCII-only systems
Processing filenames to avoid character encoding issues

Alternatives:

iconv – iconv handles broad character set conversion, while Unac focuses specifically on accent removal.
python-unicodedata – Python's built-in library offers similar normalization but requires a Python runtime environment.
