Editing Precomposed character (section)

== Chinese characters ==
In theory, most [[Chinese characters]] as encoded by [[Han unification]] and similar schemes could be treated as precomposed characters, since they can be reduced (decomposed) to their constituent [[radical (Chinese characters)|radical and phonetic]] components with [[Chinese character description languages]].  Such an approach could reduce the number of characters in the character set from tens of thousands to just a few thousand. On the other hand, a decomposed character set would introduce challenges for searching and editing software and require more bytes of encoding per document. One particular challenge would be the multiple-to-multiple projections between the  set of decomposed characters and the precomposed character—one precomposed character may be decomposed into multiple different sets of decomposed characters while one set of decomposed characters could contract themselves into multiple different precomposed characters. There is no strict requirement or constraints regarding the relative position between components within a character, the form of variant and transform (narrow, widen, stretch, rotate, etc.) applied on components, nor the number of each components.
