char8_t - type for UTF-8 character representation, required to be large
enough to represent any UTF-8 code unit (8 bits). It has the same size,
signedness, and alignment as unsigned char (and. therefore, the same size
and alignment as char and signed char), but is a distinct type.

Add check for unnecessary search before insertion
...
This will warn for cases where searching in an associative container happens before insertion, like this:
```cpp
void f1(std::set<unsigned>& s, unsigned x) {
if (s.find(x) == s.end()) {
s.insert(x);
}
}
void f2(std::map<unsigned, unsigned>& m, unsigned x) {
if (m.find(x) == m.end()) {
m.emplace(x, 1);
} else {
m[x] = 1;
}
}
```
In the case of the map it could be written as `m[x] = 1` as it will create the key if it doesnt exist, so the extra search is not necessary.
I have this marked as `performance` as it is mostly concerning performance, but there could be a copy-paste error possibly, although I dont think thats common.
