* 'th'. Other times it is its own primary element. Another
* example is '₨'. Sometimes its a currency symbol. Sometimes it
* is an 'R' followed by an 's'.
*
* Additionally an expanded element should always sort directly
* after its first element due to they way sortkeys work.
*
* UCA sortkey elements are of variable length but no collation
* element should be a prefix of some other element, so I think
* this is safe. See:
* - https://ssl.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_collation_design.htm
* - http://site.icu-project.org/design/collation/uca-weight-allocation
*
* Additionally, there is something called primary compression to
* worry about. Basically, if you have two primary elements that
* are more than one byte and both start with the same byte then
* the first byte is dropped on the second primary. Additionally
* either \x03 or \xFF may be added to mean that the next primary
* does not start with the first byte of the first primary.
*
* This shouldn't matter much, as the first primary is not
* changed, and that is what we are comparing against.
*
* tl;dr: This makes some assumptions about how icu implements
* collations. It seems incredibly unlikely these assumptions
* will change, but nonetheless they are assumptions.
