Member Typedef Documentation

typedef wxUint32 wxUniChar::value_type

A type capable of holding any Unicode code point.

We do not use wchar_t as it cannot do the job on Win32, where wchar_t is a 16-bit type (wchar_t* is encoded using UTF-16 on Win32).

Member Function Documentation

bool wxUniChar::GetAsChar

(

char *

c

)

const

Returns true if the character is representable as a single byte in the current locale encoding.

This function only returns true if the character can be converted in exactly one byte, e.g. it only returns true for 7 bit ASCII characters when the encoding used is UTF-8.

It is mostly useful to test if the character can be passed to functions taking a char and is used by wxWidgets itself for this purpose.

Parameters

c	An output pointer to the value of this Unicode character as a char. Must be non-NULL.

Returns

true if the object is an 8 bit char and c was filled with its value as char or false otherwise (c won't be modified then).
