U+223B was added to Unicode in version 1.1 (1993). It belongs to the block Mathematical Operators in the Basic Multilingual Plane.

This character is a Math Symbol and is commonly used, that is, in no specific script.

The glyph is not a composition. It has a Neutral East Asian Width. In bidirectional context it acts as Other Neutral and is mirrored. In text U+223B behaves as Alphabetic regarding line breaks. It has type Other for sentence and Other for word breaks. The Grapheme Cluster Break is Any.

The Wikipedia has the following information about this codepoint:

In mathematics, a

homothety(orhomothecy, orhomogeneous dilation) is a transformation of an affine space determined by a pointScalled itscenterand a nonzero numberλcalled itsratio, which sends

in other words it fixes

S, and sends anyMto another pointNsuch that the segmentSNis on the same line asSM, but scaled by a factorλ. In Euclidean geometry homotheties are the similarities that fix a point and either preserve (ifλ> 0) or reverse (ifλ< 0) the direction of all vectors. Together with the translations, all homotheties of an affine (or Euclidean) space form a group, the group ofdilationsorhomothety-translations. These are precisely the affine transformations with the property that the image of every lineLis a line parallel toL.In projective geometry, a homothetic transformation is a similarity transformation (i.e., fixes a given elliptic involution) that leaves the line at infinity pointwise invariant.

In Euclidean geometry, a homothety of ratio

λmultiplies distances between points by |λ| and all areas byλ^{2}. The first number is called theratio of magnificationordilation factororscale factororsimilitude ratio. Such a transformation can be called anenlargementif the scale factor exceeds 1. The above-mentioned fixed pointSis calledhomothetic centerorcenter of similarityorcenter of similitude
