The need seems quite obvious when mixing LTR and RTL languages, e.g. embed an American company or English phrase in a RTL language text.

- phkahler 5y agoWhy does it need to overwrite or obscure existing characters?
- _nalply 5y agoThe Right-To-Left Override (U+202E) does not obscure nor overwrite existing characters. It is an instruction to switch the text direction to right-to-left like for Arabic and Hebrew. In the article it is shown how this can be misused to show executable files as a different file type: file[U+202e]fdp.exe shown as fileexe.pdf ~~~~~~~~^^^^^^^ | |--- read this right-to-left, i.e. exe.pdf |----------- this is the Unicode character Right-To-Left Override
- kazinator 5y agoIt certainly obscures and overwrites. When you replace "fdp.exe" by "exe.pdf", you're obscuring and overwriting the leading "f" by "e", then the "d" by "x" and so on.
- dtech 5y agoIt doesn't overwrite or obscure, it switches rendering direction. E.g. \u202E\u41\u42\u43 starts outputting from the right: \u41 from the right, then 42, then 43. That's CBA, altough in normal English you'd render that as ABC.
