I'm not particularly well versed in how Han characters are handled by Unicode, but it would appear that the character is shared. U+9580 sits under the CJK Unified Ideographs block. As wikipedia describes it:
The Chinese, Japanese and Korean (CJK) scripts share a common background, collectively known as CJK characters. In the process called Han unification, the common (shared) characters were identified and named "CJK Unified Ideographs". As of Unicode 8.0, Unicode defines a total of 80,388 CJK Unified Ideographs
Under the Han unification effort, one important point to note is:
Modern Chinese, Japanese and Korean typefaces typically use regional or historical variants of a given Han character.

Mostly yes, but some variant characters are encoded under different code points since they are seen as different characters.
