 <p>These variables specify the locale for the <code>LC_CTYPE</code> category,
 which determines the type of characters,
 e.g., which characters are whitespace.
-This category also determines the character encoding, that is, whether
-text is encoded in UTF-8, ASCII, or some other encoding.  In the
-&lsquo;<samp>C</samp>&rsquo; or &lsquo;<samp>POSIX</samp>&rsquo; locale, all 
characters are encoded as a
-single byte and every byte is a valid character.
-In more-complex encodings such as UTF-8, a sequence of multiple bytes
-may be needed to represent a character, and some bytes may be encoding
-errors that do not contribute to the representation of any character.
-POSIX does not specify the behavior of <code>grep</code> when patterns or
-input data contain encoding errors or null characters, so portable
-scripts should avoid such usage.  As an extension to POSIX, GNU
-<code>grep</code> treats null characters like any other character.
-However, unless the <samp>-a</samp> (<samp>--binary-files=text</samp>) option
-is used, the presence of null characters in input or of encoding
-errors in output causes GNU <code>grep</code> to treat the file as binary
-and suppress details about matches.  See <a

Directory Selection</a>.
