I came across something I can't search for what it means.
#define DEFAULT_KEY L"text"
What does 'L' mean or do?
Other example that I found
wcscat(xpath, L"\\");

It means the string literal has type const wchar_t*, which is a type different that const char*. It is usually used to store Unicode strings.
Some APIs (particularly the Windows API) use this type all over the place.

The L prefix denotes a wide character/string literal; i.e., it is of type wchar_t instead of char. Unicode based programs typically use wide strings, while ANSI/ASCII based programs typically do not.
