List of all members.

Detailed Description

This class is a vprintf-like formatter for Utf8Str strings. It is identical to Utf8StrFmt except that its constructor takes a va_list argument instead of ellipsis.

Note that a separate class is necessary because va_list is defined as |char *| on most platforms. For this reason, if we had two overloaded constructors in Utf8StrFmt (one taking ellipsis and another one taking va_list) then composing a constructor call using exactly two |char *| arguments would cause the compiler to use the va_list overload instead of the ellipsis one which is obviously wrong. The compiler would choose va_list because ellipsis has the lowest rank when it comes to resolving overloads, as opposed to va_list which is an exact match for |char *|.
