* Target is CopyConstructible [20.1.3].
* Target is DefaultConstructible, meaning that it is possible to default-initialize an object of that type [8.5, 20.1.4].
The character type of the underlying stream is assumed to be `char` unless either the `Source` or the `Target` requires wide-character streaming, in which case the underlying stream uses `wchar_t`, `char16_t` or `char32_t`. Wide-character streaming is currently detected for:
The character type of the underlying stream is assumed to be `char` unless either the `Source` or the `Target` requires wide-character streaming, in which case the underlying stream uses `wchar_t`. Following types also can use `char16_t` or `char32_t` for wide-character streaming:
* Single character: `wchar_t`, `char16_t`, `char32_t`
* Arrays of characters: `wchar_t *`, `char16_t *`, `char32_t *`, `const wchar_t *`, `const char16_t *`, `const char32_t *`
* Single character: `char16_t`, `char32_t`
* Arrays of characters: `char16_t *`, `char32_t *`, `const char16_t *`, `const char32_t *`
* Strings: `std::basic_string`, `boost::containers::basic_string`
* `boost::iterator_range<WideCharPtr>`, where `WideCharPtr` is a pointer to wide-character or pointer to const wide-character

[section Changes]
* [*boost 1.53.0 :]
* Much better input and output streams detection for user defined types.
* [*boost 1.52.0 :]
* Restored compilation on MSVC-2003 (was broken in 1.51.0).
