Freetype unicode on Windows - freetype2

Question

I'm using Freetype 2.5.3 on a portable OpenGL application.
My issue is that i can't get unicode on my Windows machine, while i get them correctly on linux-based systems (lubuntu, OSX, Android)
i'm using the famous arialuni.ttf (23mb) so i'm pretty sure it contains everything. In fact, i had this working in my previous Windows installation (Win7), then re-installed Win7 from another source and now unicode is not working right.
Specifically when i draw a string, then only latin are rendered while unicode are getting skipped. I dug deeper and i found that character codes are not what they should be in wstring. For example, i'm using some greek letters in the string like γ which i know it should have a code point of 947.
My engine just iterates the wstring characters and drives the above code point to another vector that holds texture coordinates so i can draw the glyph.
The problem is that on my Windows 7 machine, the wstring does not give me 947 for a γ, but instead it gives me a 179. In addition, the character of Ά returns as 2 characters of 206 code (??) instead of one of 902.
It's like simple iterating a wstring, like:
for(size_t c=0,sz=wtext.size();c<sz;c++) {
uint32_t ch = wtext[c]; // code point
...
}
This is only happening on my newly installed Win7; it worked before on another Win7 system, along with my all linux machines. Now it's broken on this, and also on my XP virtual machine.
I don't use any wide formatting functions on this, just like:
wstring wtext = L"blΆh";
In addition, i can see my glyphs being rendered correctly in my OpenGL texture, so not a font issue either. My font generator uses the greek range of ~900-950 code points to collect the glyphs.
I add the code points per language with this:
FT_UInt charcode;
FT_ULong character = FT_Get_First_Char(face, &charcode);
do {
character = FT_Get_Next_Char(face, character, &charcode);
...
} while(charcode);

Answer 1

Not sure why but i fixed it by saving the file as UTF-8 BOM, rather UTF-8 (i had it by default).
