/* |

|
This explicit template specialisation reads a single unicode character from the stream. |
| 851 |
|
|
| 852 |
|
By default, the compiler treats wchar_t as if it were a typedef for unsigned short. This means |
| 853 |
|
that we cannot distinguish between an unsigned short and a wchar_t in the library. To be most |
| 854 |
|
consistent with previous practice, we add this explicit specialisation to ensure that a single |
| 855 |
|
unsigned short is read and written as a character. |
| 856 |
|
|
| 857 |
|
If you wish to read and write unsigned shorts as integers, we recommend you consider making |
| 858 |
|
wchar_t a native type by using the /Zc:wchar_t compiler switch. |
