Hi, A "unicode" RTL is of course great for targeting legacy Windows platforms, but for those of us on Linux, UTF-8 is the way. To this end, it would be helpful to add a paragraph on the wiki page underlining how to retain the single-byte RTL; or, if no user action is necessary, mention that, to set minds at ease. Thank you for this hard work!
