我在使用 PHP 的htmlentities()/htmlspecialchars()函数时遇到了一些问题。我正在转换的字符串包含字符 –（html 等效项是 '&oelig'），但两者htmlentities()都htmlspecialchars()没有转换此字符。

当我跑去get_html_translation_table(HTML_ENTITIES)查看 PHP 正在使用的转换表时，我注意到该œ字符丢失了，但还存在其他韧带（如æ( &aelig)）。为什么是这样？我应该以不同的方式转换 – 字符吗？

作为参考，我正在运行 PHP 5.3.14，这是来自的输出get_html_translation_table(HTML_ENTITIES)：

我尝试使用 PHP 5.4.5 并正确输出 &oelig。所以我不能真正测试这个，但我猜是因为它不在默认使用的 iso-8859-1 的实际字符集中。它们在补充字符集中。尝试使用 ISO-8859-15

htmlentities($s,  ENT_COMPAT | ENT_HTML401, "ISO-8859-15");
