Should I pass an std::function by const-reference?
...
As usual in C++11, passing by value/reference/const-reference depends on what you do with your argument. std::function is no different.

Singleton: How should it be used
... a new object instead of referencing an existing one? Since this is tagged C++, let's use an example from that language. Do you often accidentally write
std::ostream os;

float minimum_distance(vec2 v, vec2 w, vec2 p...

What is Unicode, UTF-8, UTF-16?
...erally, you'll have to use a library that supports UTF, such as ICU for C, C++ and Java. In any case, if you want to input/output something other than the default encoding, you will have to convert it first.
