// This is done by defining a set of N template function taking 1..N arguments
// (currently, N is set to 30 in this header). These functions are just thin
-// wrappers around another variadic function (@a impl) and the only thing
-// the wrapper does is that it normalizes the arguments passed in so that
-// they are of the type expected by variadic functions taking string
-// arguments, i.e., char* or wchar_t*, depending on the build:
+// wrappers around another variadic function ('impl' or 'implUtf8' arguments,
+// see below) and the only thing the wrapper does is that it normalizes the
+// arguments passed in so that they are of the type expected by variadic
+// functions taking string arguments, i.e., char* or wchar_t*, depending on the
+// build:
// * char* in the current locale's charset in ANSI build
-// * whchar_t* in the Unicode build
+// * char* with UTF-8 encoding if wxUSE_UNICODE_UTF8 and the app is running
+// under an UTF-8 locale
+// * wchar_t* if wxUSE_UNICODE_WCHAR or if wxUSE_UNICODE_UTF8 and the current
+// locale is not UTF-8
+//
+// Note that wxFormatString *must* be used for the format parameter of these
+// functions, otherwise the implementation won't work correctly.
