The base ones 474 operate using the character set of the platform Perl is running on. The ones 475 with an C<_A> suffix operate on the ASCII character set, and the ones with an 476 C<_L1> suffix operate on the full Latin1 character set. All are unaffected by 477 locale and by C<use bytes>. 478 479 For ASCII platforms, the base function with no suffix and the one with the 480 C<_A> suffix are identical. The function with the C<_L1> suffix imposes the 481 Latin-1 character set onto the platform. That is, the code points that are 482 ASCII are unaffected, since ASCII is a subset of Latin-1. But the non-ASCII 483 code points are treated as if they are Latin-1 characters. For example, 484 C<isSPACE_L1()> will return true when called with the code point 0xA0, which is 485 the Latin-1 NO-BREAK SPACE. 486 487 For EBCDIC platforms, the base function with no suffix and the one with the 488 C<_L1> suffix should be identical, since, as of this writing, the EBCDIC code 489 pages that Perl knows about all are equivalent to Latin-1. The function that 490 ends in an C<_A> suffix will not return true unless the specified character also 491 has an ASCII equivalent. 492 493 =for apidoc Am|bool|isALPHA|char ch 494 Returns a boolean indicating whether the specified character is an 495 alphabetic character in the platform's native character set. 496 See the L<top of this section|/Character classes> for an explanation of variants 497 C<isALPHA_A> and C<isALPHA_L1>. 498 499 =for apidoc Am|bool|isASCII|char ch 500 Returns a boolean indicating whether the specified character is one of the 128 501 characters in the ASCII character set.
