The "at sign" is typographically known as commat, as in "commercial at". A few years ago, it was assigned a morse code symbol, the first change in morse in a veryh long time. —Preceding unsigned comment added by 112.203.198.236 (talk) 08:23, 11 January 2010 (UTC)
Incorrect values for ℛ (U+211B SCRIPT CAPITAL R), etc
This article, as it currently exists, is not correct. It shows a script capital R in this unicode block (U+1D400 ... U+1D7FF), but there is no script capital R here. Instead, unicode has a script capital R elsewhere (at U+211B). The same is true for a variety of other characters (looking at Unicode code chart U1D400 (PDF), which is currently an external link but should be a reference, it looks like Swiss cheese). If we want to stick with presenting these characters by Unicode block, we should just take out all those characters. If we want to keep together related characters, we need to get rid of the numbers (or come up with some presentation which can show the numbers, which might be in a different block, somehow).

- Code point U+1D4AD <reserved-1D4AD> (is not assigned). The linked Unicode page (U1D400.pdf) says on page 7: <reserved>, meaning: not assigned (not a character). Then it refers specifically to {U+211B ℛ SCRIPT CAPITAL R (ℛ, ℛ). So the facts Kingdon writes are correct.
- But I don't understand the bigness of the problem. Anyone can change the chart here. See this edit. Go ahead if you like. And if it becomes Swiss cheese -- if its Unicode, it'll be OK. -DePiep (talk) 20:44, 18 September 2010 (UTC)
