Function name:
CLEAN

Category:
Text

Summary:
Removes non-printable characters from the supplied text string.

Syntax:
CLEAN(Text)

Returns:
Returns a text string that corresponds to the argument string, after removal of non-printable characters.

Arguments:
Text is a text string (in quotation marks), or a reference to a cell containing such a text string, which is the string to be "cleaned".

Additional details:
CLEAN removes a specific set of non-printable characters that are defined in the C0 Controls and Basic Latin Unicode block. The exact non-printable characters that will be removed by CLEAN are:


 * Any character in the code point range U+0000 to U+001F (inclusive).
 * The character with code point U+007F.

Space characters (code point U+0020) are not removed by CLEAN.

CLEAN does not currently remove any non-printable characters defined in other Unicode code blocks and thus is not totally compliant with ODF 1.2.
