Constant | Value
--- | ---
`QChar::Center` | `3`
`QChar::Dual` | `1`
`QChar::OtherJoining` | `0`
`QChar::Right` | `2`

## Member Function Documentation

### `[static]` QChar QChar::fromAscii(char c)

Converts the ASCII character c to it's equivalent QChar. This is mainly useful for non-internationalized software.

An alternative is to use QLatin1Char.

See also fromLatin1() and unicode().

### Joining QChar::joining() const

Returns information about the joining properties of the character (needed for certain languages such as Arabic).

### `[static]` Joining QChar::joining(uint ucs4)

This is an overloaded function.

Returns information about the joining properties of the UCS-4-encoded character specified by ucs4 (needed for certain languages such as Arabic).

### char QChar::toAscii() const

Returns the Latin-1 character value of the QChar, or 0 if the character is not representable.

The main purpose of this function is to preserve ASCII characters used in C strings. This is mainly useful for developers of non-internationalized software.

Note: It is not possible to distinguish a non-Latin 1 character from an ASCII 0 (NUL) character. Prefer to use unicode(), which does not have this ambiguity.

Note: This function does not check whether the character value is inside the valid range of US-ASCII.
