ZSCAN match pattern encoding issue

[silvertype]

lettuce-core version : 5.0.4-RELEASE

I'm trying to find keys with patterns in the values.
So I created a secondary index key consisting of id and name with sorted sets.

redis-cli works well

127.0.0.1:7001> zscan idx_key 0 match *가전* count 10000
1) "0"
2)  1) "10001396:\xec\x98\x81\xec\x83\x81\xea\xb0\x80\xec\xa0\x84\xec\x95\xa1\xec\x84\xb8\xec\x84\x9c\xeb\xa6\xac"
    2) "0"
    3) "10000209:\xec\x9d\x8c\xed\x96\xa5\xea\xb0\x80\xec\xa0\x84"
    4) "0"
    5) "10000211:\xec\x9d\xb4\xeb\xaf\xb8\xec\x9a\xa9\xea\xb0\x80\xec\xa0\x84"
    6) "0"
    7) "10001850:\xec\x9d\xb4\xeb\xaf\xb8\xec\x9a\xa9\xea\xb0\x80\xec\xa0\x84\xec\x95\xa1\xec\x84\xb8\xec\x84\x9c\xeb\xa6\xac"
    8) "0"
    9) "10000801:\xea\xb0\x80\xec\xa0\x84\xec\xa0\x9c\xed\x92\x88"
   10) "0"

but, lettuce client zscan result 0.

ScanArgs scanArgs = ScanArgs.Builder.matches("*가전*").limit(Integer.MAX_VALUE);
ScoredValueScanCursor ret = lettuceCient.zscan(key, ScanCursor.INITIAL, scanArgs);

on monitor

"ZSCAN" "idx_key" "0" "MATCH" "*\x00\x04*" "COUNT" "2147483647"

가전 -> \x00\x04
The correct utf-8 encoding value is \xea\xb0\x80\xec\xa0\x84

Why does it change like this?

The match argument of ScanArgs is encoded using ASCII by taking each character and using its integer value to convert it to bytes. I think it would make sense to apply UTF8 conversion to be on the safe side.
