What 🄄 means
One character carries the digit-comma form.
🄄 predates Unicode: ARIB STD-B24, Japan's digital-broadcast data standard, lists it as code 9235. Unicode's proposal called it “number comma” and sought standard codes because broadcast symbols without standard codes went into private-use font slots, where users could assign conflicting meanings. The reading is literal: 3 followed by ,.
Can text cleanup change 🄄?
Yes: compatibility normalization turns it into 3,.
Unicode's compatibility mapping is ASCII 3 plus ,. Compatibility normalization folds special forms into plain text, so software using it can replace one character with two. If a file needs this exact form, avoid that cleanup.
