[15] RFR: 8239383: Support for Unicode 13.0

[Joe Wang]

+1

They are from the reference files, but it's interesting to note the 
ranges in Blocks.txt (that Character.java follows) for Tangut Supplement 
(18D00..18D8F) and CJK Unified Ideographs Extension G (30000..3134F) are 
slightly different from those in the online pdf files 
(http://www.unicode.org/charts/PDF/Unicode-13.0/), where Tangut 
Supplement showed "Range: 18D00–18D08" and CJK Unified Ideographs 
Extension G "Range: 30000–3134A".

Best,
Joe
