Detailed Description

RWUString::Pad defines an iostream manipulator that can be used to insert the contents of an RWUString ustr into an output stream os, padding the string with the specified fill character until os.width() code points have been written to the stream.

If the length of ustr is greater than os.width(), the string is truncated and no padding occurs. If os.width() is zero, the entire contents of the string are inserted into the stream and no padding occurs.

An RWUString::Pad instance is only valid as long as the source string remains unchanged. Do not create persistent instances of this class; this class should only be instantiated as a temporary in an insertion expression.

RWUString ustr = ...;
std::cout << RWUString::Pad(ustr, static_cast<RWUChar32>('.'))
          << std::endl;
