有没有办法将html流中的unicode Symbol字体转换为其等效的utf8实体？

即. 0xf067(作为unicode符号html实体)到希腊小写字母gamma(U 03B3 akaγ在标准utf8中)

解决方法:

最后,我设法使用符号来进行unicode映射

然后使用iconv从unicode转换为utf8(作为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 (
