Request for Inclusion of Subscript for the English L etter “y”

Dear Unicode

I am writing to formally request the inclusion of a subscripted version of
the English letter “y” within the unicode font dictionary. In mathematical
analysis and physics, the letter “y” is frequently employed to denote one
component of a system decomposed into two spatial dimensions, namely “x”
and “y.” A subscript for “y” is therefore indispensable to distinguish
between these dimensions and facilitate precise notation of individual
components.

If it is not feasible to implement this subscript, I would appreciate an
explanation regarding any technical or procedural constraints preventing
its addition. Thank you for considering this request, as it would
significantly enhance the clarity and effectiveness of notation in
mathematical and scientific applications.

Thank you,
Kaiyuan
