Note that lexicon support in HALCON is currently not aimed at natural languages. Rather, it is intended as a post-processing step in OCR applications that only need to distinguish between a limited set of not more than a few thousand valid words, e.g., country or product names. When the lexicon file contains entries with special, non-ASCII characters, it is expected to be encoded in UTF-8. However, old lexicon files which use the local 8-bit encoding, can still be loaded as long as they contain at least one byte sequence, which cannot be misinterpreted as UTF-8 character.
