NAME

SYNOPSIS
#include <courier-unicode.h>
-
uint32_t unicode_category_lookup(unicode_char c);
-
int unicode_isalnum(unicode_char c);
-
int unicode_isalpha(unicode_char c);
-
int unicode_isblank(unicode_char c);
-
int unicode_isdigit(unicode_char c);
-
int unicode_isgraph(unicode_char c);
-
int unicode_islower(unicode_char c);
-
int unicode_ispunct(unicode_char c);
-
int unicode_isspace(unicode_char c);
-
int unicode_isupper(unicode_char c);
DESCRIPTION
unicode_category_lookup() looks up the
m[blue]unicode character's categorizationm[][1].
unicode_category_lookup() returns a 32 bit value. The value's
UNICODE_CATEGORY_1
bits specify the first level of the unicode character's category, with
UNICODE_CATEGORY_2,
UNICODE_CATEGORY_3, and
UNICODE_CATEGORY_4
bits specifying the 2nd, 3rd, and 4th level, if given. A value of 0 for each corresponding bit set indicates that no category is specified for this level, for this character; otherwise the possible values are defined in
<courier-unicode.h>.
The remaining functions implement comparable equivalents of their non-unicode versions in the standard C library, as follows:
unicode_isalnum()
-
Returns non-0 for all
unicode_isalpha() or
unicode_isdigit().
unicode_isalpha()
-
Returns non-0 for all
UNICODE_CATEGORY_1_LETTER.
unicode_isblank()
-
Return non-0 for
TAB, and all
UNICODE_CATEGORY_2_SPACE.
unicode_isdigit()
-
Returns non-0 for all
UNICODE_CATEGORY_1_NUMBER
|
UNICODE_CATEGORY_2_DIGIT, only (no third categories).
unicode_isgraph()
-
Returns non-0 for all codepoints above
SPACE
which are not
unicode_isspace().
unicode_islower()
-
Returns non-0 for all
unicode_isalpha() for which the character is equal to
unicode_lc(3)
of itself.
unicode_ispunct()
-
Returns non-0 for all
UNICODE_CATEGORY_1_PUNCTUATION.
unicode_isspace()
-
Returns non-0 for unicode_isblank() or for unicode characters with linebreaking properties of
BK,
CR,
LF,
NL, and
SP.
unicode_isupper()
-
Returns non-0 for all
unicode_isalpha() for which the character is equal to
unicode_uc(3)
of itself.
