A variable of type WideChar, which has a synonym of UnicodeChar (type UnicodeChar = WideChar;) , is exactly 2 bytes in size, and usually contains one Unicode character in UTF-16 encoding. As it is impossible to encode all Unicode code points (a code point normally corresponds to a character) in 2 bytes, two WideChars may be needed to encode a single code point.

As of version 3 of Free Pascal, the Char datatype is a synonym for an AnsiChar. However, in the future the Free Pascal compiler may consider Char a synonym for WideChar.
