What means
A Japanese dictionary links it to 窄, “narrow.” Its specialist entry treats the identification as tentative; let surrounding text confirm the sense.
The 2023 Unicode proposal grouped it with 621 other ideographs for China’s GB 18030 update, a standard for exchanging text, and said the submitted set was in use. That dates the encoding, not the written form’s origin.
In 2023, Firefox could show CJK Extension I characters as boxes even with a supporting font installed; Mozilla fixed the bug in Firefox 120/121. A box can signal display failure, not a different character.

1Why does show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
