More than one way of String handling. Depending on the requirements of your applicationyou can work with UTF-8, UTF-16, or legacy encodings. The following code snippetsdemonstrate all three variants. All examples create the same Japanese output, butaccept the string input in different formats.The first example works with Unicode UTF-8 and uses the Unicode::String modulewhich is part of most modern Perl distributions, and available on CPAN). Since Perlworks with UTF-8 internally no explicit UTF-8 conversion is required:use Unicode::String qw(utf8 utf16 uhex);...PDF_set_parameter($p, "textformat", "utf8");$font = PDF_load_font($p, "Arial Unicode MS", "unicode", "");PDF_setfont($p, $font, 24.0);PDF_set_text_pos($p, 50, 700);PDF_show($p, uhex("U+65E5 U+672C U+8A9E"));The second example works with Unicode UTF-16 and little-endian byte order:PDF_set_parameter($p, "textformat", "utf16le");$font = PDF_load_font($p, "Arial Unicode MS", "unicode", "");PDF_setfont($p, $font, 24.0);PDF_set_text_pos($p, 50, 700);PDF_show($p, "\xE5\x65\x2C\x67\x9E\x8A");The third example works with Shift-JIS. Except on Windows systems it requires access tothe 90ms-RKSJ-H CMap for string conversion:PDF_set_parameter($p, "SearchPath", "../../../resource/cmap");$font = PDF_load_font($p, "Arial Unicode MS", "cp932", "");PDF_setfont($p, $font, 24.0);PDF_set_text_pos($p, 50, 700);PDF_show($p, "\x93\xFA\x96\x7B\x8C\xEA");Unicode and legacy encoding conversion. For the convenience of PDFlib users we listsome useful string conversion methods here. Please refer to the Perl documentation formore details. The following constructor creates a Unicode string from a byte array:$logos="\x{039b}\x{03bf}\x{03b3}\x{03bf}\x{03c3}\x{0020}" ;The following constructor creates a Unicode string from the Unicode character name:$delta = "\N{GREEK CAPITAL LETTER DELTA}";The Encode module supports many encodings and has interfaces for converting betweenthose encodings:use Encode 'decode';$data = decode("iso-8859-3", $data);# convert from legacy to UTF-836 Chapter 2: PDFlib Language Bindings
