m_pUIElement = Parse(T2CW(pszMarkup));
//m_pUIElement = Parse(pszMarkup);

So, somehow the parser has changed?

Also notice that XTToolkit has two versions of Parse:

CXTPMarkupUIElement* Parse(LPCSTR lpszBuffer);
CXTPMarkupUIElement* Parse(LPCWSTR lpszBuffer);

So I'm right.  

It's Codejock that has changed method. 

Show me how to add the above xml tag, please.

Thank.

If you don't have an <xml ....> tag, then you don't have XAML, why don't you try adding one.  You could use markup pad to see what you need to have in there in order to be valid XAML.

Sorry, but You are wrong. 

As you can see, i don't use something like:  <?xml encoding="utf-8" ?>

Prior to v.17.0.0 all worked fine, with any chars.

After v. 17.0.0 all chars with accents will made a wrong markup string. 

Typically I use a MFC CString to generate and set the Markup text.

Does it require that I run Unicode or wide-character for the markup text?

I have added French accent symbols to Xtreme SuitePro ActiveX v17.3.0\Samples\Common\VB\MarkupPad\Markups\Welcome.xaml and opened it in MarkupPad VB sample, here is the screenshot:

So, as a solution, please make sure you use a proper XML/XAML editor and use save a file as UTF-8 and to make sure specify this in XML header as:

<?xml encoding="utf-8" ?>
