+ Overview of wxString conversions, implicit and explicit:
+
+ - wxString has a std::[w]string-like c_str() method, however it does
+ not return a C-style string directly but instead returns wxCStrData
+ helper object which is convertible to either "char *" narrow string
+ or "wchar_t *" wide string. Usually the correct conversion will be
+ applied by the compiler automatically but if this doesn't happen you
+ need to explicitly choose one using wxCStrData::AsChar() or AsWChar()
+ methods or another wxString conversion function.
+
+ - One of the places where the conversion does *NOT* happen correctly is
+ when c_str() is passed to a vararg function such as printf() so you
+ must *NOT* use c_str() with them. Either use wxPrintf() (all wx
+ functions do handle c_str() correctly, even if they appear to be
+ vararg (but they're not, really)) or add an explicit AsChar() or, if
+ compatibility with previous wxWidgets versions is important, add a
+ cast to "const char *".
+
+ - In non-STL mode only, wxString is also implicitly convertible to
+ wxCStrData. The same warning as above applies.
+
+ - c_str() is polymorphic as it can be converted to either narrow or
+ wide string. If you explicitly need one or the other, choose to use
+ mb_str() (for narrow) or wc_str() (for wide) instead. Notice that
+ these functions can return either the pointer to string directly (if
+ this is what the string uses internally) or a temporary buffer
+ containing the string and convertible to it. Again, conversion will
+ usually be done automatically by the compiler but beware of the
+ vararg functions: you need an explicit cast when using them.
+
+ - There are also non-const versions of mb_str() and wc_str() called
+ char_str() and wchar_str(). They are only meant to be used with
+ non-const-correct functions and they always return buffers.
+
+ - Finally wx_str() returns whatever string representation is used by
+ wxString internally. It may be either a narrow or wide string
+ depending on wxWidgets build mode but it will always be a raw pointer
+ (and not a buffer).
