Code changes

Note Always test code fixes in a controlled environment before you apply the fixes to your production computers.
To resolve this problem, follow these steps:

Create a new function in the WordManagement codeunit (5054) as follows:

LOCAL PROCEDURE InsertCharSet(MergeFileName@1000000000 : Text[260]) : Text[250];
VAR
NewLine : Text[250];
f: File;
f2: File;
b: Integer;
MergeFileNameServer: Text[250];

IF NOT ISSERVICETIER THEN
BEGIN
IF EXISTS(MergeFileName+'$') THEN
ERASE(MergeFileName+'$');
WITH f DO BEGIN
TEXTMODE(TRUE);
WRITEMODE(FALSE);
OPEN(MergeFileName);
END;
WITH f2 DO BEGIN
TEXTMODE(TRUE);
WRITEMODE(TRUE);
CREATE(MergeFileName+'$');
END;
END
ELSE
BEGIN
MergeFileNameServer := RBAutoMgt.ServerTempFileName(Text029,'.HTM');
UPLOAD(Text021, '', Text032, MergeFileName, MergeFileNameServer);
WITH f DO BEGIN
TEXTMODE(TRUE);
WRITEMODE(FALSE);
OPEN(MergeFileNameServer);
END;
WITH f2 DO BEGIN
TEXTMODE(TRUE);
WRITEMODE(TRUE);
CREATE(MergeFileNameServer+'$');
END;
END;

REPEAT
b:=f.READ(NewLine);
IF NewLine='<html>' THEN
NewLine:= '<HTML><META charset=windows-1253>';
f2.WRITE(NewLine);
UNTIL f.POS>=f.LEN;
f.CLOSE;
f2.CLOSE;

IF ISSERVICETIER THEN
BEGIN
ERASE(MergeFileNameServer);
RENAME(MergeFileNameServer+'$', MergeFileNameServer);
DOWNLOAD(MergeFileNameServer,Text035,'',Text032,MergeFileName);
END
ELSE
BEGIN
ERASE(MergeFileName);
RENAME(MergeFileName+'$', MergeFileName);
END;
EXIT (MergeFileName);

Change the four digit code in the following line in the InsertCharSet function in the WordManagement codeunit (5054):
```
NewLine:= '<HTML><META charset=windows-1253>';
```
Note "1253" is the correct code to use where the Microsoft Dynamics NAV client language is Greek (GR). Change this four digit code to the Windows charset code for your Microsoft Dynamics NAV client language. For example, "1257" is the correct code for Latvian (LV).

Change the code in the CreateWordAttachment function in the WordManagement codeunit (5054) as follows:
Existing code

...

CREATE(wrdApp,FALSE,TRUE);
Attachment."File Extension" := GetWordDocExt(wrdApp.Version);
wrdDoc := wrdApp.Documents.Add;

ParamInt := 7; // 7 = HTML
wrdDoc.MailMerge.OpenDataSource(MergeFileName,ParamInt);
...

Replacement code

...
IF ISCLEAR(wrdApp) THEN
CREATE(wrdApp,FALSE,TRUE);

wrdDoc := wrdApp.Documents.Add;
wrdDoc.MailMerge.MainDocumentType := 0; // 0 = wdFormLetters
ParamInt := 7; // 7 = HTML

// Add the following line.
MergeFileName:=InsertCharSet(MergeFileName); 

wrdDoc.MailMerge.OpenDataSource(MergeFileName,ParamInt);
...

Change the code in OpenWordAttachment the function in the WordManagement codeunit (5054) as follows:
Existing code

...
IF ISCLEAR(wrdMergefile) THEN
CREATE(wrdMergefile,FALSE,TRUE);
MergeFileName := RBAutoMgt.ClientTempFileName(Text029,'.HTM');
CreateHeader(wrdMergefile,TRUE,MergeFileName);
IF ISCLEAR(wrdApp) THEN
CREATE(wrdApp,FALSE,TRUE);
...

Replacement code

IF ISCLEAR(wrdMergefile) THEN
CREATE(wrdMergefile,FALSE,TRUE);
MergeFileName := RBAutoMgt.ClientTempFileName(Text029,'.HTM');

// Add the following line.
MergeFileName:=InsertCharSet(MergeFileName); 

IF ISCLEAR(wrdApp) THEN
CREATE(wrdApp,FALSE,TRUE);
...

Change the code in the ExecuteMerge function in the WordManagement codeunit (5054) as follows:
Existing code

...
wrdDoc := wrdApp.Documents.Open(MainFileName);
wrdDoc.MailMerge.MainDocumentType := 0;
Window.UPDATE(6,Text013);
ParamInt := 7; // 7 = HTML
wrdDoc.MailMerge.OpenDataSource(MergeFileName,ParamInt);
Window.UPDATE(6,STRSUBSTNO(Text014,TempDeliverySorter."Correspondence Type"));
...

Replacement code

...
wrdDoc := wrdApp.Documents.Open(MainFileName);
wrdDoc.MailMerge.MainDocumentType := 0;
Window.UPDATE(6,Text013);
ParamInt := 7; // 7 = HTML

// Add the following line.
MergeFileName:=InsertCharSet(MergeFileName); 

wrdDoc.MailMerge.OpenDataSource(MergeFileName,ParamInt);
Window.UPDATE(6,STRSUBSTNO(Text014,TempDeliverySorter."Correspondence Type"));
...

Change the code in the ShowMergedDocument function in the WordManagement codeunit (5054) as follows:
Existing code

...
ParamInt := 7; // 7 = HTML
wrdDoc.MailMerge.OpenDataSource(MergeFileName,ParamInt);
ParamInt := 9999998; // 9999998 = wdToggle
wrdDoc.MailMerge.ViewMailMergeFieldCodes(ParamInt);
END;
WordHandler(wrdDoc,Attachment,WordCaption,IsTemporary,MainFileName,IsInherited);
CLEAR(wrdMergefile);
CLEAR(wrdDoc);
CLEAR(wrdApp);
DeleteFile(MergeFileName);
...

Replacement code

...
ParamInt := 7; // 7 = HTML

// Add the following line.
MergeFileName:=InsertCharSet(MergeFileName); 

wrdDoc.MailMerge.OpenDataSource(MergeFileName,ParamInt);
ParamInt := 9999998; // 9999998 = wdToggle
wrdDoc.MailMerge.ViewMailMergeFieldCodes(ParamInt);
END;
WordHandler(wrdDoc,Attachment,WordCaption,IsTemporary,MainFileName,IsInherited);
CLEAR(wrdMergefile);
CLEAR(wrdDoc);
CLEAR(wrdApp);
