hexStringToCodePoint fails for hexString that contains "-"

[johnguild]

Line 393 of Client.java fails with hexString containing dashm
sample are 1f3c3-2642 , 1f3c3-2640

private String hexStringToCodePoint(String hexString) {
      int codePoint = Integer.parseInt(hexString, 16 );
      return new String(new int[]{codePoint}, 0, 1);
 }

Dunno a workaround so a temporary fallback would be better than showing a shortname, maybe like

 private String hexStringToCodePoint(String hexString) {
    if(hexString.contains("-")){
        String[] parts = hexString.split("-");
        hexString = parts[0];
    }
      int codePoint = Integer.parseInt(hexString, 16 );
      return new String(new int[]{codePoint}, 0, 1);
 }
