They only show Latin1 is faster. Maybe they don't
understand that their UTF16 is simply slower:

StringCompressLogging.cyrillic                                   avgt 
25    81.210 ±   0.334   ns/op
StringCompressLogging.latin                                      avgt 
25    56.337 ±   0.357   ns/op

Thats a very depressing nonsense frankly.
