What 셓 means
It means “three” in Middle Korean.
The earliest attestation of 셓 is in Seokbo Sangjeol, a Korean text from 1447; modern Korean writes the word 셋.
Keep 셓 for historical Korean
The 1446 introduction to Hangul, Hunminjeongeum, says it was designed to write Korean speech, which differed from Chinese. Hangul letters combine into syllable blocks: 셓 combines initial consonant ㅅ, vowel ㅔ, and final consonant ㅎ.
In Middle Korean, final ㅎ could change or disappear depending on the following particle, a short grammatical ending attached to a word. As that pattern changed, ㅎ was lost and the word developed into 셋.
A deeper link to a numeral from Baekje, an ancient Korean kingdom, has been proposed, but that connection remains uncertain.
Historical and scholarly: it marks an older Korean spelling, so it belongs in historical texts rather than ordinary present-day writing.
For modern Korean “three,” use 셋; reserve 셓 for the historical form.

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.
