How to input unicode in table cell

Zhu Johnson · Post by **Zhu Johnson** » Wed Jun 25, 2008 3:23 pm

I am new to RichViewEdit.
I came upon a problem when inputing chinese characters into tables. It is Ok when I type in characters in richViewEdit, but characters are displayed as squares when typed in table cells. AddNLATag works ok.
All unicode properties for styles are set to true, defUnicodeStyle =1, RTFReadProperties.UnicodeMode := rvruOnlyUnicode
Should I change any other setting?Or something I am wrong?
Thank you in advance.

I just created a test project - placed RichViewEdit, RVStyle and Button on the form, and added the following code:

Code: Select all

procedure TForm1.FormCreate(Sender: TObject);
var i: Integer;
begin
  RichViewEdit1.RTFReadProperties.UnicodeMode := rvruOnlyUnicode;
  RichViewEdit1.Clear;
  for i := 0 to RVStyle1.TextStyles.Count-1 do
    RVStyle1.TextStyles[i].Unicode := True;
  RichViewEdit1.Format;
end;

procedure TForm1.Button1Click(Sender: TObject);
var table: TRVTableItemInfo;
begin
  table := TRVTableItemInfo.CreateEx(2,2,RichViewEdit1.RVData);
  table.BorderWidth := 2;
  table.CellBorderWidth := 1;
  RichViewEdit1.InsertItem('', table);
end;

Since I can type both Russian and Greek in table cells, they contain Unicode text, as expected:

Thank you very much. The problem still remains even though I did exactly as you instructed. Is it possiblly because Chinese characters are two byte character?

No, in Unicode it must not be a problem.
Please send me a project reproducing this problem.

The test project is made just as the instructions in your posts, not any unusual. I saved the content of the component. It is like what follows:
{\rtf1\ansi\ansicpg0\uc1\deff0\deflang0\deflangfe0{\fonttbl{\f0\fnil Arial;}}{\colortbl;\red0\green0\blue0;\red0\green0\blue255;\red0\green255\blue255;\red0\green255\blue0;\red255\green0\blue255;\red255\green0\blue0;\red255\green255\blue0;\red255\green255\blue255;\red0\green0\blue128;\red0\green128\blue128;\red0\green128\blue0;\red128\green0\blue128;\red128\green0\blue0;\red128\green128\blue0;\red128\green128\blue128;\red192\green192\blue192;\red255\green255\blue255;\red255\green255\blue255;\red128\green128\blue128;\red212\green208\blue200;}

Inside which, \'b9\'a4 should be correct items outside the table, just as what I typed in and showed up correctly. Inside the table the code related became '\00\'u0

Please give very precise step-by-step instructions how to reproduce this problem. For me, all is ok, I can type Chinese text in table cells using phonetic IME, and they are displayed properly.
