Acroforms fonts & encoding

Hello,

  I have some question about form and editting.

1.  If I create and edit Text Field. The form value is saved into /V property like string with specific encoding (UTF-16, UTF-8).  I would like to confirm that those values ​​are Unicode values, not in "Text".

2. If I create Text Field and select specific font for form in Adobe, then the font is create with specific encoding. How the Adobe select encoding for specific font?

For instance:

If I selected this font "YuGothicUI". The  Adobe creates type0 font with this encoding "UniJIS-UTF16-H".

If I selected this font "Arial". The Adobe create truetype font with this encoding "WinAnsiEncoding".

If I selected this font "CourierStd". The Adobe create type1 font with this encoding "WinAnsiEncoding".

Thank you

David
