I put © in C++ comments all the time.  Every time I touch an old file that 
still uses (c), I update it.  All of the C++ compilers I use cope with this 
just fine.

UTF-8 isn’t an “escape sequence” system, by the way.  It’s interpreted by the 
terminal, but it isn’t part of the terminal protocol.  You tell your local 
terminal what character encoding you want it to use as part of the locale 
setting.

UTF-8 is no more an “escape sequence” than would be setting your terminal into 
EBCDIC mode or changing it from US-English to UK-English.

And if you think that latter has no effect on the keyboard input 
interpretation, try it, then see what happens when you try to “cd ~/foo”.  I 
have to fix that every time I re-flash my Raspberry Pi with Raspbian, which 
defaults to expect a British English keyboard.  I suppose they think that’s 
fair revenge for the decades of  software from US developers that blindly 
assumes US-English keyboards. :)
