I forgot to say that HTML provides a standard element for this: <abbr>mu rho</abbr>, where you can add the implied semantic of the full abbreviation in an attribute (in a separate plain-text stream), including the possible substitution rule for an alternate rendering symbol (as an image, or SVG glyph also encodableseparately in the document itself and represented in another attribute by a linking reference).
