Although Unicode text layout systems are introduced into modern text processing softwares, still legacy character encodings are widely used for
Indic scripts in South and South East Asia to work with systems missing intelligent text layout functionalities.
Some de-jure or de-facto legacy standards are used for some scripts, but there are scripts whose encodings was not standardized before ISO 10646. If the document uses the fonts with unstandardized encodings, usually the text data extraction from the document is difficult.
In this paper, we take a concrete example of such script: Khmer script. It is suppored by Unicode standard, not fully supported by applications, and no legacy encodings were standardized.
We investigate the encodings in the freely distributed Khmer TrueType fonts and propose algorithm to identify which encoding is used in the fonts. By the algorithm, the text extraction of the document including legacy TrueType fonts can be automated. |
