Decomposition Type - None
None is the assigned value indicating that a character has no canonical or compatibility decomposition mapping. It signifies that the character is not composed of a sequence of other characters, nor does it have a format-specific expansion, such as a ligature, superscript, or fraction form. In effect, this value marks the character as a base or standalone unit within the textual system, meaning it cannot be algorithmically reduced to a simpler or alternate representation. For most common letters, digits, and punctuation, this is the default, while only specific symbols or precomposed forms carry a different value. When None applies, the character’s shape and identity are considered original, not derived from any other character combination.
