When transcribing poetic meter (scansion <https://en.m.wikipedia.org/wiki/Scansion>), it is common to use two symbols above the line (usually a breve [U+306 ̆] for stressed syllables and a solidus / slash [U+2F /] for unstressed syllables) to indicate stress patterns. Ex:
̆ / ̆ / ̆ / ̆ / ̆ / When I consider how my light is spent (John Milton, On His Blindness) Other symbols used in place of the breve are a cross / x (U+D8 × or U+78 x) or bullet (U+B7 · or U+2022 •). This approach, however, is problematic; the lack of a combining slash above character means that two lines of text must be used, and any non-monospaced font (or any platform where multiple consecutive spaces are truncated into one by default, such as HTML) makes keeping the annotations properly aligned with the text difficult or impossible — depending on your email client, the above example may be entirely misaligned. Being able to use combining diacritics for scansion would make these problems obsolete and enable a semantic transcription of meter. Would a proposal to add a combining solidus above (and possibly a combining reversed solidus above to support Hamer, Wright, and Trager-Smith notations) be supported?
