...on Windows and some characters in string literals may be automatically changed. Because, at this state, the UTF-8 encoding of R source files on Windows is a fake Unicode as it can handle only 256 different ANSI characters in reality.

Hello, There is a long-lasting problem with processing UTF-8 source code in R on Windows OS. As Windows do not have "UTF-8" locale and R passes source code through OS before executing it, some characters are "simplified" by the OS before processing, leading to undesirable changes. Minimalistic example: Let's type "?" (LATIN SMALL LETTER R WITH CARON) in RGui

...characters that cannot be represented in the native encoding.

...s should not be blamed for that the design _today_ does not seem perfect for _todays_ systems (and how could they have guessed at that time Windows will still not support UTF-8 as native encoding today).
