If its possible to use Collator of ICU collation service which is base on both simultaneously :
Locale base like "ko_KR" ( coll = ucol_open("ko_KR", &status) )
Customized Rules ie "tailoring" ( coll = ucol_openRules(rlz, rlen, UCOL_OFF,UCOL_TERTIARY,NULL,&status) )
Collator_Final = Collator_Locale + Collator_customize_rule
If yes, then please suggest how we can use collator base on both at same time?
There was a reply on the mailing list to your question here
To summarize and expand:
ucol_getRules()
ko_KR
) with your custom rules.
