Try and null terminate your strings. This worked for me implementing a renderer in GDI
void r_draw_text(const char* text, mu_Vec2 pos, mu_Color color) {
char buff[1024] = { 0 };
strcat(buff, text);
strcat(buff, "\0");
SelectObject(Memhdc, hFont);
SetBkMode(Memhdc, TRANSPARENT);
SetTextColor(Memhdc, RGB(color.r, color.g, color.b));
ExtTextOutA(Memhdc, pos.x, pos.y, ETO_OPAQUE, NULL, (LPCSTR)buff, sizeof(text), NULL);
}
or since you are using C++ try a std::string and somestring.c_str() to retrieve the char*
I think it is indeed reading into the next byte and not terminating properly, I think this might how GDI (and maybe cairo?) are handling string termination.

I haven't had a chance to test this yet, but something tells me that'll do it
