Chinese character 𩛯

Both — each old reference files it under a different word. A 1666 supplement to the Ming-era dictionary Zihui, 《字彙補》, first spells its sound in fanqie — the old way of writing a pronunciation with two characters, here 古冏切 for jiǒng — and then says "same as 𩚱", a nearly vanished character glossed "sated". The Kangxi Dictionary repeats that citation, which is why the equation still surfaces when the character is looked up today.

The second record sits on a different shelf. A reference chart of the small-seal forms behind the Shuowen Jiezi — 《崇義篆體字形表》, for the Han-dynasty dictionary, compiled around 100 CE, that first analysed that early script — lists 𩛯 as the seal form of 餓 (è), the ordinary character for "hungry".

These are not two claims about one word. One tradition read the graph as a variant of a rare word for "full"; the other records it as an old seal shape filed under the word for "hungry". Which of the two stands behind a sighting tells you how to read it — and a character this rare is usually met inside one of those catalogues.

Why is such a rare character on your screen at all?

Because Unicode's Han repertoire is built from records like these. 𩛯 sits in CJK Extension B — the annex of over 42,000 little-used ideographs for the Chinese, Japanese and Korean scripts — assembled from classical dictionaries, old literature and national character lists so sources like those can be quoted digitally. Taiwan's CNS 11643 standard and Japan's Moji Joho Kiban project carry it too; a catalogue entry, not modern use, is what keeps the graph on the map.

Rarity has a visible side effect: many everyday fonts skip Extension B characters, so the glyph can appear as a hollow box while nearby text renders fine — unless the system quietly borrows a font that covers it. On a font that draws it, the left half is the 食 "food" radical — the same component shared by 餓 "hungry" and 飽 "full", the two words this graph has been filed under.
