Similar to 䦧 U+49A7.

The place name is read "Hishirimo", and the reading of this character, "hishiri", does not suggest any obvious semantic relationship with the standard reading of 䦧 or 䦧, which is "seme(gu)" meaning "blame, curse, attack" etc. 䦧 or 䦧 are probably not interchangeable with UTC-03233, hence not unifiable.

The verb "hishiru" is found in 『精選版 日本国語大辞典』 as "to shout" and in 『和歌山弁Explorer』 (Wakayama dialect) as "to be furious". Perhaps it is also in the local dialect of "Hishirimo". Neither meaning is far from "blame, curse, attack".
