Decomposition Type in Unicode categorizes characters based on how they can be decomposed into simpler components. This property aids in text processing, allowing characters to be represented consistently across different contexts and systems.
As of Unicode Version 15.0.0, there are 18 different Decomposition Type.
Canonical Decomposition, Compatibility, Enclosing Mark, Final Presentation Form and Font specific Glyph are some examples of Unicode Decomposition Type.
