That wouldn’t be compliant with existing languages and future languages
might use any existing character.

Can’t good editors display tabs in a different color when required ?

I rarely escape quotes.
In a text, I use ’ (U+2019) as an apostrophe and «»“”‘’ as quotes, so I
don’t need to escape them.
When I use PHP to generate some HTML code, I try to alternate simple and
double quotes as much as possible. That way I rarely need to escape them.

To replace the semicolon in C and the languages based on its syntax?

Aren’t you trying to reinvent APL?
