Convert Dynamic A2 to A3 to support Arabic/Chinese/Russian

I have an existing project in dynamic A2 and it has been modified to support non-latin languages such as Chinese, Russian. The data file is in .txt file. However, we now need to support Arabic and it is impossible in A2. Therefore, the entire file needs to be converted to A3 while preserving all the previous work, including the entry map (which is a map) and also all the other languages and insert the Arabic language into the new data file to make sure that it supports. All other languages must also work.
