Add UTF-8 support to TextConsole!!
...
continuous-integration/drone/push Build is passing
Not much support, since the font only covers codepoints from U+0000 to U+00FF,
(Basic Latin & Latin Extended-A), but unprintable code-points are rendered as ONE box per code-point,
instead of multiple garbage characters.
So it's Unicode-aware, even if it can't print most characters.

Add a 'pure' variant of cstyle_format which is infallible
...
If we cannot fail to output, it doesn't make sense to propagate errors. So if you're SURE there are no errors, use pure_cstyle_format().
If, however, output can fail, use cstyle_format().
This has a drawback of adding quite a bit of code duplication to Format.cpp.
Some of it is dealt using templates, but some code still remains duplicate.

Here's one advantage of Rust over C++:
Immutability by default. In Rust, you have to mark a variable as mutable, whereas in C++ you have to mark it as immutable.
What's the problem here? Usually, most variables don't need mutability. Thus we end up with const all over the place.
