To keep the average and maximum bucket size low, I made codepoints
< 4000 more granular and code points >= 4000 less granular. This
could be tweaked further for sure to reach more even sized buckets.
Bucket stats before:
- 773 buckets
- smallest has 1 entries
- largest has 1804 entries
- median size is 66 entries
- average size is 45.394566623545 entries
Bucket stats after:
- 698 buckets
- smallest has 1 entries
- largest has 1792 entries
- median size is 16 entries
- average size is 50.272206303725 entries
