The 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.
