It works great!

Still I have a problem...

I use the following code:

void __fastcall TForm1::FormCreate(TObject *Sender)

{

RichViewEdit1->RTFReadProperties->UnicodeMode = rvruOnlyUnicode;

for(int i=0; i<RVStyle1->TextStyles->Count; i++)

{

RVStyle1->TextStyles->Items[i]->Unicode = true;

//RVStyle1->TextStyles->Items[i]->Charset = RUSSIAN_CHARSET;

}

RichViewEdit1->Format();

}

//---------------------------------------------------------------------------

When I copy text from the clipboard or IE and I start typing, everything

works. I can type English text in the Russian text.

But when I start the application without any text, and I try to type English

text, I get strange squares. (like this スススススススス)

Do you have a clue?

Thank you.

(It doesn't matter if it is in Russian of English).
