## Detailed Description

This class represents a single Unicode character.

It can be converted to and from `char` or `wchar_t` and implements commonly used character operations.

## 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).

## Constructor & Destructor Documentation

wxUniChar::wxUniChar | ( |  | ) |

Default ctor.

wxUniChar::wxUniChar | ( | char | c | ) |

Create a character from the 8-bit character value c using the current locale encoding.

wxUniChar::wxUniChar | ( | unsigned char | c | ) |

## 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).
