Using iconv with Custom Table (Linux) Create a mapping file stmzh.map : stmzh to unicode
The task means converting text encoded in this custom character set into standard Unicode (typically UTF-8) for modern interoperability. 2. Understanding the Encoding (Hypothetical but Practical) Assuming STMZH is an 8-bit encoding (0x00–0xFF) where the first 128 characters (0x00–0x7F) match ASCII, and the upper range (0x80–0xFF) contains special letters, symbols, or control codes unique to a system (e.g., a microcontroller firmware, a point-of-sale terminal, or a Russian/Czech variant). a microcontroller firmware
