Hello.
UTS #10 has been updated, so terminator primary weight for Hangul
is implemented in Unicode::Collate.
Usage: $collator = Unicode::Collate->new(hangul_terminator => $term);
$term, the value for the 'hangul_terminator' key, should be
a positive integer lesser than primary weights of any Hangul Jamo.
If $term is false or hangul_terminator key does not exist,
insertion of terminator weights will not be performed.

Collation elements of hangul-related characters like enclosed hangul
letters should be modified in accordance with the terminator weight,
or they will not be equivalent to standard Hangul syllables.
Example of a collation element table tailored for classic Hangul
is shown below (a part, with quaternary weights omitted);
where primary weights: TERM = 0x100, initial G = 0x18A0,
vowel A = 0x1870, final G = 0x1840, etc.
#Jongseong should have lesser weight.
11A8 ; [.1840.0020.0002] # JONGSEONG KIYEOK
11A9 ; [.1840.0020.0002][.1840.0020.0002] # JONGSEONG SSANGKIYEOK
#Jungseong should have middle weight.
1161 ; [.1870.0020.0002] # JUNGSEONG A
1176 ; [.1870.0020.0002][.1874.0020.0002] # JUNGSEONG A-O
1162 ; [.1870.0020.0002][.1879.0020.0002] # JUNGSEONG AE
1163 ; [.1871.0020.0002] # JUNGSEONG YA
1175 ; [.1879.0020.0002] # JUNGSEONG I
#Choseong should have greater weight.
1100 ; [.18A1.0020.0002] # CHOSEONG KIYEOK
#Non-conjoining Hangul should include TERM like this.
326E ; [.18A1.0020.0006][.1870.0020.0006][.0100.0000.0000] # CIRCLED K A
1101 ; [.18A1.0020.0002][.18A1.0020.0002] # CHOSEONG SSANGKIYEOK
1102 ; [.18A2.0020.0002] # CHOSEONG NIEUN
1113 ; [.18A2.0020.0002][.18A1.0020.0002] # CHOSEONG NIEUN-KIYEOK
