Specifying unicode strings

I´m trying to use some Icelandic characters in a program:

wchar_t *unichars = L"áéíóúýðöæþÁÉÍÓÚÝÐÖÆÞ";
std::wcout << unichars << std::endl;

The output I get in the console isn't great:

ßΘφ≤·²≡÷µ■┴╔═╙┌▌╨╓╞▐

Any idea on what is going wrong?

Set your locale to Icelandic:

_tsetlocale(LC_ALL,L"Icelandic");

Thanks for the reply, that does help the console output (although it still isn't quite right).

I think the actual problem I was having was the encoding dev studio was using to save the file. Somehow the characters appear fine in the editor but only compile correctly when I saved the file in "Unicode - codepage 1200" format.

There is no codepage 1200. Icelandic uses code page 1252 (Western European) so you shouldn't have to change your language settings at all. I think you're getting things messed up somehow with Unicode and Ansi/OEM strings.

I am sure it is the file encoding, the original file is encoded in Western and if I open the file in a text editor the string reads:

"abdefghijklmnoprstuvxyzÃ¡Ã©ÃÃ³ÃºÃ½Ã°Ã¾Ã¦Ã¶"

through some dev studio magic the editor there shows the correct values (but it doesn't run correctly):

"abdefghijklmnoprstuvxyzáéíóúýðþæö"

If I change the file to UTF-16 then the text editor and the runtime all agree. Could it be that the file is using MBCS?

I'm using dev studio 2008, if you select file->save as, then click the arrow by the save and select "save with encoding...", one of the options is "Unicode - Codepage 1200".
Looking this up on wikipedia shows that this is:

# 1200 — UCS-2LE Unicode little-endian

Which editor?

If I open it with SciTE, it reports the encoding as "code page property" and the string isn't shown correctly. If I select UTF-8 as the enoding it shows correctly. I'm guessing the c++ compiler is reading this file in ascii giving the problem. There isn't a BOM on this file which is what was going wrong I guess.

In addition to David's suggestion - If you are using the console as output you need also CharToOem() or CharToOemBuff()

Jon17-Jul-09 1:11

The console was only for testing, the font has to be set correctly as well I think. Anyway it's all working again now.

1. Using Visual Studio?
2. Hope the laguage settings from control panel are changed to icelandic.

Jon17-Jul-09 1:10

17-Jul-09 1:10

That's not entirely necessary I think, although that would probably ensure the default file encoding was correct.

Another approach is to specify the unicode characters by number, something like:

wchar_t *unichars = L"\u00FE\u00D1...

This would work (if I knew all the codes) but wouldn't be very readable.

Yes.[^]

Besides the problem described in the article (conversion from wide char to multibyte), there are additional problems: the default console font on Windows does not support Unicode.

i am working in a code, in which they have used DHTML Edit Control(Dhtmled.ocx) to implement IE HTML editor sort of application. pasteHTML method is crashing when it get some strange HTML text. this is not happening at all the time. i have added the code below.
but i cannot add the HTML code which is causing the problem ,since it is too huge text. this is happening at client's place only.

this happens with Windows XP , IE6-SP3

it is working fine in Windows 2003 server with IE 7.

I am passing HTML text as 1'st argument.

i have searched all over the place in the net, but nobody discussed about the problem.
i know microsoft dropped supporting DHTML Edit for long time before, but we can not migrate it to MSHTML, , because it will take long time for me to rewrite exact the code to simulate DHTML Edit control wrapper class in MSHTML, i have to give a fix for time being,

Please throw me a clue if anybody have an idea, if

1. is there any way to find out a HTML tag which is causing the crash,

2. any workaround for pasteHTML method , .

void CDHTMLEdit::ReplaceSel(LPCTSTR lpszNewText,bool bHTML/* = true */)
{
try
{
CHTMLSelectionObject SelObj = GetDom().GetSelection();

CString strText = SelObj.GetType();

LPDISPATCH lpIDispatch= SelObj.createRange();

IHTMLTxtRange * lpTxtRange;
if(S_OK != lpIDispatch->QueryInterface(IID_IHTMLTxtRange,(void **)&lpTxtRange))
{
lpIDispatch->Release();
return;
}

if(bHTML)
{
CComBSTR bstrReplaceText = lpszNewText;

lpTxtRange->pasteHTML(bstrReplaceText);

}
else
{
CComBSTR bstrReplaceText = lpszNewText;
lpTxtRange->put_text(bstrReplaceText);
}

lpTxtRange->collapse(false);
lpTxtRange->select();

lpTxtRange->Release();
lpIDispatch->Release();
}
catch(COleDispatchException * pDE)
{
FILETRACE(_T(" COleDispatchException caught in CDHTMLEdit::ReplaceSel."));
pDE->Delete();
ASSERT(FALSE);
}
catch(...)
{
FILETRACE(_T("CDHTMLEdit::ReplaceSel - Unhandled exception caught"));
ASSERT(FALSE);

When the above code is compiled with VS 6.0 compiles without any error, but if the same is compiled in VS 2008 following is the error
“error C4430: missing type specifier - int assumed. Note: C++ does not support default-int”
Can you please let me know what causes this error.

Are you instantiating the class? If yes, how are you instantiating the class? Where is the default constructor?

The constructor is not public, so how can you create an object like that? Also, I don't see why would you receive a C4430 for this. I thought it must complain about not being able to access a protected function. (~~C2448 or whatever, I ain't sure - don't have a compiler here~~ Searched for it, found it - C2248[^]).

Look at the placement of the reference specifier (the &). It' meant to come after the type you want to reference. So, the compiler is seeing const&base as (const&)==type and (base)==parameter name.

Solution - use const base&.
