 # Unicode: The wide-character set
 
-A wide character is a 2-byte multilingual character code. Any character in use in modern computing worldwide, including technical symbols and special publishing characters, can be represented according to the Unicode specification as a wide character. Developed and maintained by a large consortium that includes Microsoft, the Unicode standard is now widely accepted.
+A wide character is a 2-byte multilingual character code. Any character in use in modern computing worldwide, including technical symbols and special publishing characters, can be represented according to the Unicode specification as one or more wide characters.

 A wide character is of type **`wchar_t`**. A wide-character string is represented as a **`wchar_t[]`** array. You point to the array with a `wchar_t*` pointer.
