What 𝓻 means
Read 𝓻 as a distinct symbol; the equation tells you what it denotes. Mathematical notation can use plain, bold, italic, and script letters for different quantities in one expression; a math script r is one such choice, not a universal label.
Bold script, also called bold calligraphic, is a cursive-style mathematical alphabet. The STIX project began in 1995; its mathematical alphabet proposal reached Unicode in 1998 and was accepted in 1999. The proposal carried established typesetting distinctions into plain-text characters because collapsing styled letters could change a formula.
Why does 𝓻 change shape across math fonts?
Unicode leaves the exact drawing to each math font. Its chart glyph is an example, not a blueprint; fonts can give script letters different loops, weight, and slant while preserving their role as distinct mathematical characters.
Use it when your formula defines a separate styled symbol; in ordinary prose, format a regular r instead of repurposing a math alphabet.

Questions people ask
1Can compatibility normalization turn 𝓻 into plain r?
Yes. Compatibility normalization, specifically Unicode's NFKC form, maps mathematical styled letters to basic Latin ones, so 𝓻 becomes ordinary r. That conversion removes its style distinction.
