22 * All encoding names, sorted: *** A L P H A B E T I C ***
23 *
24 * All names must be without irrelevant chars, search routines use
25 * isalnum() chars only. It means ISO-8859-1, iso_8859-1 and Iso8859_1
26 * are always converted to 'iso88591'. All must be lower case.
27 *
28 * The table doesn't contain 'cs' aliases (like csISOLatin1). It's needed?
