What 器 means
Yes: it maps to 器, with no separate everyday meaning.
器 can mean a vessel or container, a tool, or an organ; 器 carries the same ordinary range as its older form. It is a distinct encoded form, not a separate everyday word.
In JIS X 0213:2000, this compatibility form was included for round-trip conversion: text could pass through the Japanese standard and return with its original character intact.
Can Unicode normalization change 器?
Yes: all four normalization forms can turn it into 器.
NFC and NFD, as well as NFKC and NFKD, can replace this source-form character with its unified counterpart. If the exact source form matters, retain the original character in stored text before a normalization step that would fold it.
Technical or archival: it marks a preserved Japanese source form, not a special conversational tone.
Normalization may turn 器 into 器 before the source form is recorded.
