The 'empty()' method is more efficient for checking if a string is empty compared to comparing it with an empty string literal.
The default constructor 'std::wstring()' is more efficient for creating an empty string compared to using a string literal.
The 'clear()' method is more efficient for clearing a std::wstring compared to assigning it an empty string literal.

Replaced copying of the 'sources' variable with move semantics to improve performance.
By moving instead of copying, we avoid unnecessary copying of data and enhance efficiency.

Replaced 'std::optional::value()' with '*' operator to improve performance.
Using 'std::optional::value()' involves additional overhead compared to using the '*' or '->' operators. This change ensures more efficient access to the underlying value of the optional when you are certain that it contains a value.

Replaced 'at()' method with 'operator[]' to improve performance.
The 'at()' method performs bounds checking, which can introduce overhead. Using 'operator[]' bypasses this check and can improve performance when you are certain that the index is within bounds.

Passing cheap-to-copy arguments by reference can sometimes lead to decreased performance. This change ensures that the argument is passed by value, which is more efficient in cases where the argument is inexpensive to copy.

Replaced 'emplace' with 'try_emplace' to avoid unnecessary copies or moves when insertion fails.
The 'emplace' function does not guarantee that arguments will not be copied or moved if insertion is not successful. Using 'try_emplace' ensures that arguments are only copied or moved if the insertion actually takes place, thus improving performance.

The 'current.reset(lang.release())' expression is equivalent to 'current = std::move(lang)'.
Changed 'current.reset(lang.release())' to 'current = std::move(lang)' to improve code clarity and performance.

It's better to use '= default;' syntax instead of empty constructor and destructor body.
Using '= default;' can help the compiler generate more optimal code.

Expression's value is copied at variable declaration.
The variable is never modified. Consider declaring it as a reference.
Changed variables to be a reference to avoid unnecessary copy.
