Answer 1

Got it working:

public static TiffOutputField getTiffOutputFieldKeyword(
    TiffOutputSet outputSet, String metaDataToChange) {
TiffOutputField imageHistoryPre = outputSet
        .findField(TiffConstants.EXIF_TAG_XPKEYWORDS);
if (imageHistoryPre != null) {
    outputSet.removeField(TiffConstants.EXIF_TAG_XPKEYWORDS);
}

TiffOutputField tiffOutputField = new TiffOutputField(
        TiffConstants.EXIF_TAG_XPKEYWORDS,
        TiffFieldTypeConstants.FIELD_TYPE_BYTE,
        metaDataToChange.getBytes("UTF-16").length, metaDataToChange.getBytes("UTF-16"));

return tiffOutputField;
}

Just use length of Bytes in "UTF-16" and then write. Also, Make sure you trim the characters to not include any spaces. Also, please give a try by separating string with Semicolon(;) as By default Windows take semicolon separated keywords.
