Re: [dev] Getting warning [Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text()]
Hi m...@2008, Am in a need of Openoffice that runs onto DirectFB. Please can you provide some inputs on the port that you have done. Like what is the memory footprint and what all features does it support. I would really like to know more about your work on this openoffice port.

Any ideas on it?

So a better approach would be to use one of the conversion functions from rtl::OUString to RTL_TEXTENCODING_UTF8 rtl::OString (rtl::OUStringToOString, rtl::OUString::convertToString) and use the resulting rtl::OString's data in the call to pango_layout_set_text. -Stephan - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Hi, Am Working on porting OpenOffice onto DirectFB.Have completed the implementation of most of the major functionality. But facing some issues relating document font rendering. Am getting the warning Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text() for a regular document text Have used pango to render the font and implemented a PangoFontLayout class deriving from SalLayout in unx under vcl. Following is the code to implement the UTF-16 to UTF-8 conversion where i have found out the problem is arising. m_pLayoutText = new ByteString( rArgs.mpStr, rArgs.mnLength); m_pLayoutText->Convert( RTL_TEXTENCODING_UNICODE, RTL_TEXTENCODING_UTF8 ); pango_layout_set_text( m_pPangoLayout, m_pLayoutText->GetBuffer(), rArgs.mnLength ); For a simple line text properly formatted there is no problem. But Have noticed significant corruption in rendered text when 1)multiple tabs are present infont of a line in the sample doc. 2)Extra spaces are present in the original doc. 3)A space in the form of a "grey area" is present in the original doc. ...and many more instances not found yet. A removal of the above spaces and tabs removes the warning and the document is rendered cleanly without corruption. Any ideas on the same will be greatle appreciated. :) Regards, Karl -- View this message in context: http://www.nabble.com/Getting-warning--Pango-WARNING-**%3A-Invalid-UTF-8-string-passed-to-pango_layout_set_text%28%29--tp17643055p17643055.html Sent from the openoffice - dev mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
