unicode reference for retonga, citonga, votonga is incorrect

[ZacharyRMcKee]

one of the codes is duplicated (PATONGA's) and the subsequent *tonga codes are off-by-one by incrementing off of the duplicated unicode value:

U+ED8C  patonga ZBALERMORNA COMBINING PA TONGA
U+ED8C  retonga ZBALERMORNA COMBINING RE TONGA
U+ED8D  citonga ZBALERMORNA COMBINING CI TONGA
U+ED8E  votonga ZBALERMORNA COMBINING VO TONGA

should be

U+ED8C  patonga ZBALERMORNA COMBINING PA TONGA
U+ED8D  retonga ZBALERMORNA COMBINING RE TONGA
U+ED8E  citonga ZBALERMORNA COMBINING CI TONGA
U+ED8F  votonga ZBALERMORNA COMBINING VO TONGA
