I assume you’ve seen https://en.wikipedia.org/wiki/Unicode_subscripts_and_superscripts, which discusses what is and isn’t available as super/subscripts (henceforth “ss”) in Unicode. That surprised me—I would have thought that ss were markup, not characters, so there’s more of it implemented already than I’d expected. Note that there’s a superscript “y” but no subscript, which is also odd.
That page does suggest that ss as characters are sort of eschewed, and perhaps unlikely to be extended. Obviously Wikipedia isn’t official Unicode policy, either. I’m not arguing against it; I have no dog in this fight, just saw your interesting request and dug a little while waiting for a meeting to start. Will watch this discussion! From: Unicode <[email protected]> On Behalf Of Kevin Sun via Unicode Sent: Tuesday, November 5, 2024 3:08 PM To: [email protected] Subject: Request for Inclusion of Subscript for the English Letter “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
