All ideographic symbols of these three scripts are defined by the Unicode Standard,
while the number of characters included in a particular CJK font is determined by the font’s creator.
The CJK character set comprises the logographic graphemes of the Chinese, Japanese, and Korean writing systems,
known as Hanzi, Kanji, and Hanja. Their shared historical origin has resulted in a large number of overlapping forms.
Contemporary standards unify these characters into a single CJK system,
with complete normalization and the elimination of duplicates.
Unicode Standard, Version 17 (2025), defines approximately 102,000 CJK Unified Ideographs,
which together represent the total historical and modern repertoire of these three scripts.
However, the vast majority of these characters are no longer used in everyday practice
and are largely confined to classical literature, historical records, as well as personal and geographical names.
The national standards of contemporary usage include:
China — 3500 常用字
Japan — 2136 常用漢字
Korea — 1804 educational Hanja characters
After extensive research and long-term exploration, we developed our own character selection
for the InfoFORM Orach Technic CJK standard
by unifying these national standards into the CJK Set of 7740 characters,
which serves as the foundation of the future Orach Technic CJK font project.
We consider that the standards prescribed for primary, secondary, and higher education in these three countries
are fully sufficient for a font of this type,
with the possibility of controlled expansion in accordance with future developmental needs.
While working on this selection, we also identified an additional approximately 3,000 symbols
defined by Chinese standards for higher education and specialized use,
which could be implemented at a later stage as a possible extension of this version of our CJK font.
Upon completion of this work, we will create an overview of all these characters with their visual forms
and Unicode code points, as we previously did for Orach Technic Pro,
which will, we hope, make the process of symbol selection easier for many designers
who decide to develop their own version of a CJK font.
Not only will this simplify their work, but it may also encourage them to embark on this endeavor themselves.
