What 岍 means
Read it as 岍, the name of a mountain.
Taiwan's Ministry of Education lists 岍 as a form of 岍, read qiān in Mandarin. The Yu Pian, a Chinese dictionary compiled in 543, records 岍 as a mountain name.
Unicode's supplemental block supports conversion with Taiwan's CNS 11643-1992 standard for Chinese text (character-table sections 3–7 and 15). Normalization maps 岍 to 岍; adding U+FE00, a mark that selects a glyph form, after 岍 preserves the distinction.
Technical; its separate code preserves a source-text distinction.
Normalization can replace it with 岍 and erase that distinction.

1Why does 岍 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.
