Please show exactly how you have use it.

We (i.e. ICU) use ISO standard names of encodings.

Examples:

    Latin1
    Macintosh
    Windows-1251 
    UTF8
    UTF-8
    UTF-16
    KOI-8
    
ICU is smart enough to recognize the same encoding via different aliases.

I still wonder why V4MD mac/win itself was not able resolve standard
issue...

Or may be I know why.

Director itself support only MacRoman and table of mac/win conversion for
it. We use V4MD with single byte encoding, which can be any from 200+
encodings of the world except UTF16 (2 bytes) encoding.

So V4MD itself in conjunction with Vserver can handle encodings which
Director cannot. I remember that we have try to use V4MD + Vserver with
russian text and it have work (I mean between mac/win), while Director
itself again cannot handle Russian on default.

Read WIKI pages about encryption. IT describe WHERE must be called encrypted
methods.

I will recommend you do full encryption/decryption calls right in Lingo.

Vstudio can have bug in this regard. It is 100% tested to be able open dbs
created by ADKs, but I am not sure if reverse direction was tested good.
