Library encoded differently than self written program - stray char error

Question

I have a problem including a library to my C++ project. The library is written by collegues but when I try to include it in my project I get a whole bunch of error: stray character in program, namely these:

I figure this is because the library is encoded in a different way than my project, after finding several similar questions that had this error inside of the self written program. Could anyone tell me how to fix this problem? Maybe I included the library wrongly, I use Code::Blocks software and clicked "Build options" on my project, and in the Linker settings tab I included ..\WindowsAPI\libVibroTacLib.a in the Link libraries window. The #include part in my main.cpp looks like this:

#include "VibroTac.h"
#include "errorcodes.h"
#include "vibroTacTypeDef.h"
#include "VibroTacLib.dll"

Maybe this one helps http://stackoverflow.com/q/17222397/1741542. The second answer suggests the files encoded in some 16bit Unicode. — Olaf Dietsche, Oct 19 '16 at 09:13
@Olaf thank you for that. Though I don't quite understand what file I have to open because I cannot open a .dll file, can I? I tried with PSPadEditor... — Lehue, Oct 19 '16 at 09:18
*If* the source file is encoded in UTF-16, every character occupies two bytes instead of one. This would explain the "warning: null character(s) ignored". — Olaf Dietsche, Oct 19 '16 at 09:21
A DLL is not a source code file to be compiled. It's the end product. Don't try to compile the DLL. — Cheers and hth. - Alf, Oct 19 '16 at 09:23
I overlooked your final `#include "VibroTacLib.dll"`. This is explained in the second question, I mentioned. Remove this line, and you might be done. — Olaf Dietsche, Oct 19 '16 at 09:23
@Olaf when I remove the mentioned line the problem is, that the functions I call are not implemented...At least I get this error code from `errorcodes.h`. That is why I thought I would have to include the .dll as well... — Lehue, Oct 19 '16 at 09:27
Nevertheless, keep the line removed. When you get other error messages, you must figure out, what to include. Search for the missing function/method/variable names in the header files `*.h` and include these. — Olaf Dietsche, Oct 19 '16 at 09:30
Sorry to ask another stupid question @Olaf, but do you know how I should include these missing functions? For example the `vibroTac.connect()` looks like this in the `*.h` file: `virtual int CALL connect(const char* port);`. Any idea on how to implement this? — Lehue, Oct 19 '16 at 10:10
I can't tell, because I don't know this vibrotac library. If this method is already in the library, you must add it to the list of libraries used by your program. If this is a method supposed to be implemented by a derived class, you must create a new class inheriting from the base class, see [virtual function specifier](http://en.cppreference.com/w/cpp/language/virtual) for a simple example. — Olaf Dietsche, Oct 19 '16 at 10:27
@Olaf thank you for your help. It turned out the author of this library capsulatet its functionality. With another way to call the functions it works. — Lehue, Oct 19 '16 at 10:49
