SPVM::Unicode - SPVM Unicode Utilities.
use Unicode; # Get Unicode codepoints from UTF-8 string with the byte offset and proceed the offset to next UTF-8 character position my $string = "あいうえお"; my $pos = 0; while ((my $uchar = Unicode->uchar($string, \$pos)) >= 0) { # ... }
Unicode is SPVM Unicode utilities. This module privides the methods to convert UTF-8 bytes to/from Unicode codepoints.
static method INVALID_UTF8 : int ();
return -2. this means uchar function find invalid utf8.
static method is_unicode_scalar_value : int ($code_point: int) {
Check if the given value is a Unicode scalar values.
The range of Unicode scalar values are the range of Unicode code points(0 to 0x10FFFF) except for the range of surrogate code points(0xD800 to 0xDFFF).
0
0x10FFFF
0xD800
0xDFFF
static method uchar : int ($string : string, $offset_ref : int*);
Get a Unicode codepoint from UTF-8 string with the byte offset and proceed the offset to next UTF-8 character position.
If offset is over the string length, this method returns -1.
If invalid UTF-8 character is found, this method returns -2. This is the same value of the return value of ERROR_INVALID_UTF8 method.
static method uchar_to_utf8 : string ($unicode_code_point : int);
Convert a Unicode codepoint to a UTF-8 character.
If the argument value is invalid Unicode code point, this method returns undef.
static method utf8_to_utf16 : short[] ($utf8_string : string) {
Convert a UTF-8 string to a UTF-16 string.
static method utf16_to_utf8 : string ($utf16_string : short[]) {
Convert a UTF-16 string to a UTF-8 string.
static method utf32_to_utf16 : short[] ($utf32_string : int[]);
Convert a UTF-32 string to a UTF-16 string.
static method utf16_to_utf32 : int[] ($utf16_string : short[]);
Convert a UTF-16 string to UTF-32 string.
