> Characters that are represented as a 2 characters internaly by java are incorrectly converted by the function. The following test displays the problem quite nicely:
> import org.apache.commons.lang.*;
> public class J2 {
>     public static void main(String[] args) throws Exception {
>         // this is the utf8 representation of the character:
>         // COUNTING ROD UNIT DIGIT THREE
>         // in unicode
>         // codepoint: U+1D362
>         byte[] data = new byte[] { (byte)0xF0, (byte)0x9D, (byte)0x8D, (byte)0xA2 };
>         //output is: ��
>         // should be: 𝍢
>         System.out.println("'" + StringEscapeUtils.escapeHtml(new String(data, "UTF8")) + "'");
>     }
> }
> Should be very quick to fix, feel free to drop me an email if you want a patch.
