+
+#### Background
+In the domain of languages such as Chinese, Japanese, and Korean (CJK languages), encompassing the Unicode character range from 4E00 to 9FFF ([CJK Unified Ideographs](https://unicode.org/charts/PDF/U4E00.pdf)), it becomes crucial to acknowledge the intricate nuances in their typographic requirements. Despite sharing a common Unicode spectrum, each CJK language and its corresponding country may exhibit distinct typographic preferences and standards.
+
+Particularly noteworthy is the lack of uniformity in defining text sizes as either large or small within the following ranges:
+- from 18 [points][] to 22 [points][]
+- from 14 [points][] to 18 [points][] with a [computed][] [font weight][] of 700 or higher.
+
+Whether CJK characters in these ranges should be considered as "large scale" depends on the language of the text, as well as the country for which the text is designed and whose requirements must be followed. Given that these pieces of information are not readily available, the ACT rules adhere to the large text definition outlined above. This definition is applicable across all languages under the rationale of "no false positives."
