Found this using IDA 6.8 Pro
Charmap loads a DLL named GetUName.dll which has a selfnamed function and pulls the name of a unicode character using an int and loads the name into a string
In C++, it is used like GetUName(int, LPWSTR *)
In C#, it can be imported this way:
[DllImport("GetUName.dll", CallingConvention = CallingConvention.StdCall)]
public static extern int GetUName(int x, [MarshalAs(UnmanagedType.LPWStr)]string lpBuffer);
Then, create a string buffer to load name in (255 in case of large names, can be changed)
public static string charactername = new string('*', 255);
And use in the program like so:
GetUName('A', charactername);
// asteriks are still left in (* because names don't include
// any), simply cut the length so they aren't included
charactername = charactername.Substring(0, charactername.IndexOf('*') - 1);
Console.Write(charactername);
Included this in a program I wrote that inserts a character in the previously active window: https://github.com/donnaken15/quickcharmap/
