Script - Common

Common is a special script value used for characters that do not belong to any single writing system, such as punctuation marks (like commas or periods), mathematical symbols, spaces, and digits. These characters are shared across many languages and scripts, so they cannot be assigned to one specific script. Instead, they are grouped together as “Common,” allowing them to appear in text written in any language without conflicting with the script of the surrounding words. Examples include the plus sign, the question mark, and the Latin-style numerals used globally. This categorization helps software sort and render text correctly by treating these universal symbols as neutral, rather than tying them to a particular cultural or historical writing tradition.
