Strikethrough text generator

Adds a combining line through, under or across each character. Unlike the other styles this does not replace your letters — it appends an invisible mark after each one that draws over it.

That difference matters in practice. Because the letters themselves are unchanged, s̶t̶r̶i̶k̶e̶t̶h̶r̶o̶u̶g̶h̶ text is still searchable and still readable to a screen reader — the marks are simply ignored or announced as combining characters. It is the most accessible of the Unicode styling tricks for that reason. The cost is that each character now takes two codepoints, so the text doubles in length against any character limit, and some platforms normalise the marks away entirely. If the platform supports real formatting, use that instead; this is for the ones that do not, like a Twitter bio.
