Well I use English client so I couldn't feel any uncomfortable
but I notice recently my Korean friends could not use in game shop search because its buggy when type Korean.


when I try to search 린켄의 구슬 which is linken's sphere
it changed into 리ㄴ켄의 구슬 so I couldn't see any result.
칠흑왕의 지팡이 which is BKB also 치ㄹ흑왕의 지팡이

Something I know about this bug :

does not happen in English client, only happens in Korean client
seems the result disturb the korean typing system.
this bug is from dota 2 reborn, amazed no one make a report about this and yet not changed ...
