Как преобразовать шрифт Symbol в стандартный HTML-объект utf8

Наконец, мне удалось это сделать, используя карту Symbol для Unicode в

http://www.stat.auckland.ac.nz/~paul/R/CM/AdobeSym.html

затем преобразование из unicode в utf8 с помощью значка (как unicode <> utf8)

 function symbol_sanitize_string($string) { return preg_replace_callback('/([\x{f020}-\x{f0fe}]{1})/u', 'symbol_unicode_to_utf8_entity', $string); } function symbol_unicode_to_utf8_entity($wchar) { static $_SYMBOL_FONT_MAP = array ( 15696032 => 32, 15696033 => 33, 15696034 => 8704, 15696035 => 35, 15696036 => 8707, 15696037 => 37, 15696038 => 38, 15696039 => 8715, 15696040 => 40, 15696041 => 41, 15696042 => 8727, 15696043 => 43, 15696044 => 44, 15696045 => 8722, 15696046 => 46, 15696047 => 47, 15696048 => 48, 15696049 => 49, 15696050 => 50, 15696051 => 51, 15696052 => 52, 15696053 => 53, 15696054 => 54, 15696055 => 55, 15696056 => 56, 15696057 => 57, 15696058 => 58, 15696059 => 59, 15696060 => 60, 15696061 => 61, 15696062 => 62, 15696063 => 63, 15696256 => 8773, 15696257 => 913, 15696258 => 914, 15696259 => 935, 15696260 => 916, 15696261 => 917, 15696262 => 934, 15696263 => 915, 15696264 => 919, 15696265 => 921, 15696266 => 977, 15696267 => 922, 15696268 => 923, 15696269 => 924, 15696270 => 925, 15696271 => 927, 15696272 => 928, 15696273 => 920, 15696274 => 929, 15696275 => 931, 15696276 => 932, 15696277 => 933, 15696278 => 962, 15696279 => 937, 15696280 => 926, 15696281 => 936, 15696282 => 918, 15696283 => 91, 15696284 => 8756, 15696285 => 93, 15696286 => 8869, 15696287 => 95, 15696288 => 63717, 15696289 => 945, 15696290 => 946, 15696291 => 967, 15696292 => 948, 15696293 => 949, 15696294 => 966, 15696295 => 947, 15696296 => 951, 15696297 => 953, 15696298 => 981, 15696299 => 954, 15696300 => 955, 15696301 => 956, 15696302 => 957, 15696303 => 959, 15696304 => 960, 15696305 => 952, 15696306 => 961, 15696307 => 963, 15696308 => 964, 15696309 => 965, 15696310 => 982, 15696311 => 969, 15696312 => 958, 15696313 => 968, 15696314 => 950, 15696315 => 123, 15696316 => 124, 15696317 => 125, 15696318 => 8764, 15696544 => 8364, 15696545 => 978, 15696546 => 8242, 15696547 => 8804, 15696548 => 8260, 15696549 => 8734, 15696550 => 402, 15696551 => 9827, 15696552 => 9830, 15696553 => 9829, 15696554 => 9824, 15696555 => 8596, 15696556 => 8592, 15696557 => 8593, 15696558 => 8594, 15696559 => 8595, 15696560 => 176, 15696561 => 177, 15696562 => 8243, 15696563 => 8805, 15696564 => 215, 15696565 => 8733, 15696566 => 8706, 15696567 => 8226, 15696568 => 247, 15696569 => 8800, 15696570 => 8801, 15696571 => 8776, 15696572 => 8230, 15696573 => 63718, 15696574 => 63719, 15696575 => 8629, 15696768 => 8501, 15696769 => 8465, 15696770 => 8476, 15696771 => 8472, 15696772 => 8855, 15696773 => 8853, 15696774 => 8709, 15696775 => 8745, 15696776 => 8746, 15696777 => 8835, 15696778 => 8839, 15696779 => 8836, 15696780 => 8834, 15696781 => 8838, 15696782 => 8712, 15696783 => 8713, 15696784 => 8736, 15696785 => 8711, 15696786 => 63194, 15696787 => 63193, 15696788 => 63195, 15696789 => 8719, 15696790 => 8730, 15696791 => 8901, 15696792 => 172, 15696793 => 8743, 15696794 => 8744, 15696795 => 8660, 15696796 => 8656, 15696797 => 8657, 15696798 => 8658, 15696799 => 8659, 15696800 => 9674, 15696801 => 9001, 15696802 => 63720, 15696803 => 63721, 15696804 => 63722, 15696805 => 8721, 15696806 => 63723, 15696807 => 63724, 15696808 => 63725, 15696809 => 63726, 15696810 => 63727, 15696811 => 63728, 15696812 => 63729, 15696813 => 63730, 15696814 => 63731, 15696815 => 63732, 15696817 => 9002, 15696818 => 8747, 15696819 => 8992, 15696820 => 63733, 15696821 => 8993, 15696822 => 63734, 15696823 => 63735, 15696824 => 63736, 15696825 => 63737, 15696826 => 63738, 15696827 => 63739, 15696828 => 63740, 15696829 => 63741, 15696830 => 63742, ); $conv = hexdec(bin2hex($wchar[1])); $utf8 = $_SYMBOL_FONT_MAP[$conv]; return $utf8 ?

UTF-8 – это Unicode, вам ничего не нужно менять, у вас уже есть его в Unicode.

Расширяя ответ gplotino , я добавил несколько символов, не представленных, извлеченных из AdobeSymb

EDIT : Предыдущий скрипт не преобразовал некоторые символы, as). Поэтому я написал новый скрипт, который анализирует прямое десятичное значение символа символа un unicode для unicode (таблица, извлеченная здесь :

 function symbol_sanitize_string($string) { //important if you're use DOM to load html $string = preg_replace( '/charset=iso-8859-1/', 'charset=utf-8', $string ); //replace font symbols $string = preg_replace_callback('/&#(61\d+?);/i', 'symbol_alone2utf8', $string); return $string; } function symbol_alone2utf8( $match ){ return symbol2utf8( $match[1] ); } function symbol2utf8( $decimal ) { $_Symbol = array( 61472 => '020', 61473 => '021', 61474 => '022', 61475 => '023', 61476 => '024', 61477 => '025', 61478 => '026', 61479 => '027', 61480 => '028', 61481 => '029', 61482 => '02A', 61483 => '02B', 61484 => '02C', 61485 => '02D', 61486 => '02E', 61487 => '02F', 61488 => '030', 61489 => '031', 61490 => '032', 61491 => '033', 61492 => '034', 61493 => '035', 61494 => '036', 61495 => '037', 61496 => '038', 61497 => '039', 61498 => '03A', 61499 => '03B', 61500 => '03C', 61501 => '03D', 61502 => '03E', 61503 => '03F', 61504 => '040', 61505 => '041', 61506 => '042', 61507 => '043', 61508 => '044', 61509 => '045', 61510 => '046', 61511 => '047', 61512 => '048', 61513 => '049', 61514 => '04A', 61515 => '04B', 61516 => '04C', 61517 => '04D', 61518 => '04E', 61519 => '04F', 61520 => '050', 61521 => '051', 61522 => '052', 61523 => '053', 61524 => '054', 61525 => '055', 61526 => '056', 61527 => '057', 61528 => '058', 61529 => '059', 61530 => '05A', 61531 => '05B', 61532 => '05C', 61533 => '05D', 61534 => '05E', 61535 => '05F', 61536 => '060', 61537 => '061', 61538 => '062', 61539 => '063', 61540 => '064', 61541 => '065', 61542 => '066', 61543 => '067', 61544 => '068', 61545 => '069', 61546 => '06A', 61547 => '06B', 61548 => '06C', 61549 => '06D', 61550 => '06E', 61551 => '06F', 61552 => '070', 61553 => '071', 61554 => '072', 61555 => '073', 61556 => '074', 61557 => '075', 61558 => '076', 61559 => '077', 61560 => '078', 61561 => '079', 61562 => '07A', 61563 => '07B', 61564 => '07C', 61565 => '07D', 61566 => '07E', 61601 => '0A1', 61602 => '0A2', 61603 => '0A3', 61604 => '0A4', 61605 => '0A5', 61606 => '0A6', 61607 => '0A7', 61608 => '0A8', 61609 => '0A9', 61610 => '0AA', 61611 => '0AB', 61612 => '0AC', 61613 => '0AD', 61614 => '0AE', 61615 => '0AF', 61616 => '0B0', 61617 => '0B1', 61618 => '0B2', 61619 => '0B3', 61620 => '0B4', 61621 => '0B5', 61622 => '0B6', 61623 => '0B7', 61624 => '0B8', 61625 => '0B9', 61626 => '0BA', 61627 => '0BB', 61628 => '0BC', 61629 => '0BD', 61630 => '0BE', 61631 => '0BF', 61632 => '0C0', 61633 => '0C1', 61634 => '0C2', 61635 => '0C3', 61636 => '0C4', 61637 => '0C5', 61638 => '0C6', 61639 => '0C7', 61640 => '0C8', 61641 => '0C9', 61642 => '0CA', 61643 => '0CB', 61644 => '0CC', 61645 => '0CD', 61646 => '0CE', 61647 => '0CF', 61648 => '0D0', 61649 => '0D1', 61650 => '0D2', 61651 => '0D3', 61652 => '0D4', 61653 => '0D5', 61654 => '0D6', 61655 => '0D7', 61656 => '0D8', 61657 => '0D9', 61658 => '0DA', 61659 => '0DB', 61660 => '0DC', 61661 => '0DD', 61662 => '0DE', 61663 => '0DF', 61664 => '0E0', 61665 => '0E1', 61666 => '0E2', 61667 => '0E3', 61668 => '0E4', 61669 => '0E5', 61670 => '0E6', 61671 => '0E7', 61672 => '0E8', 61673 => '0E9', 61674 => '0EA', 61675 => '0EB', 61676 => '0EC', 61677 => '0ED', 61678 => '0EE', 61679 => '0EF', 61681 => '0F1', 61682 => '0F2', 61683 => '0F3', 61684 => '0F4', 61685 => '0F5', 61686 => '0F6', 61687 => '0F7', 61688 => '0F8', 61689 => '0F9', 61690 => '0FA', 61691 => '0FB', 61692 => '0FC', 61693 => '0FD', 61694 => '0FE' ); $key = $decimal; if( array_key_exists( $key, $_Symbol ) ){ if( $key <= 61487 ) $c = '0'; else $c = 'f'; $char = json_decode( '"\u' . $c . $_Symbol[ $key ] .

Этот скрипт был протестирован на преобразование больших файлов doc в html с высокой частотой математических символов.

Чтобы протестировать его из html-файла, используйте этот код:

 $string = file_get_contents( 'testfile.html' ); $string = symbol_sanitize_string( $string ); echo $string; //ensure that string is UTF-8 encoded echo mb_detect_encoding($string) . "<br>";
