有什麼辦法可以將html流中的unicode符號字體轉換爲其等效的utf8實體嗎？如何將符號字體轉換爲標準utf8 HTML實體
即。 0xf067（爲Unicode符號HTML實體）希臘小寫字母伽馬（標準UTF8 U + 03B3又名γ）

最後，我設法做到這一點使用符號爲unicode地圖在
http://www.stat.auckland.ac.nz/~paul/R/CM/AdobeSym.html
然後從Unicode轉換用的iconv爲UTF8（爲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 (

UTF-8是 Unicode的，你不需要改變什麼，你已經擁有它以Unicode。

是的，但我看不到它，因爲符號字體使用「私人使用區域」。我想根據這張地圖http://www.stat.auckland.ac.nz/~paul/R/CM/AdobeSym.html將它轉換爲它的「標準」unicode副本，所以我可以使用網絡安全字體來查看它。也許這個問題具有欺騙性，我希望我現在已經澄清了。 – gpilotino

「爲什麼不只是移動你鏈接的地圖？」因爲這將是非常低效的大型流，所以我正在尋找一個更有效的方法，而不是掃描整個文件char by char – gpilotino

這個腳本已經在大的DOC文件轉換測試，以HTML，具有高。數學符號的頻率
從HTML文件來測試它，使用此代碼：？
$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>";
