Hahmokoodeja

Hahmokoodeja is a term used to describe a family of character encoding schemes developed to represent the glyphs of the hahmo script, a constructed writing system used in linguistic experiments and speculative fiction. The name combines Finnish words meaning character (hahmo) and codes (koodeja), reflecting its role as a code-based representation of characters.

Design and scope: Hahmokoodeja encodes base characters, diacritics, ligatures, and contextual forms as discrete code points. It supports multi-script interchanges and aims to preserve visual composition when converting between fonts or rendering engines. The system emphasizes modularity, allowing new glyphs to be added without breaking existing encodings and providing normalization rules to minimize ambiguity.

Technical characteristics: code points are written in a hexadecimal form and arranged in sequences that can encode complex glyphs. It includes handling for ligatures, combining marks, directionality, and stylistic variants; interoperability with existing font formats is a key design goal, though not standardized. The approach favors human readability for researchers while remaining machine parsable for type engines.

Usage and reception: Hahmokoodeja appears mainly in academic exercises, font development for the hahmo script, and hobbyist projects involving constructed languages. It has limited adoption beyond these communities and no widely recognized standard, with several independent implementations and informal documentation.

History: The concept emerged in early 21st-century discussions of conlangs and typography as a way to formalize how glyphs are encoded for analysis and rendering. It remains a niche topic, often discussed alongside Unicode-inspired encoding schemes and other character-encoding experiments.
