--- Comment #51 from Damjan Jovanovic damjan.jov@gmail.com --- The first problem is that X11 apps seems have an extremely liberal interpretation of what "text/html" means. Using the readclipboard.c tool from bug 22987, and fetching TARGETS (which is the list of all possible data that can be pasted) and then the text/html target gives the following:
=============== Firefox 27.0.1: =============== $ ./readclipboard TARGETS TIMESTAMP TARGETS MULTIPLE SAVE_TARGETS text/html text/_moz_htmlcontext text/_moz_htmlinfo UTF8_STRING COMPOUND_TEXT TEXT STRING text/x-moz-url-priv

which is the HTML fragment (with CSS?) and a leading <meta> tag, in UTF-8, with no byte order mark.
So X11 apps have made a real hash of the "text/html" target, and a clipboard implementation wishing to paste text/html must autodetect the charset and byte order, as well as be very liberal in parsing the HTML that comes out :-(.
Windows apps, by comparison, expect UTF-8 and a special format with the entire HTML document and headers giving offsets to the start and end of the fragment within the document (http://msdn.microsoft.com/en-us/library/aa767917%28v=vs.85%29.aspx).
Wine will correctly export text/html to X11 apps, as of commit 1bd13dec61ae693637c6514b9d35e29597f6ed6a by Vincent Povirk on 22 November 2009, which added X11DRV_CLIPBOARD_ExportTextHtml(), which convert's Windows's HTML to X11's text/html by cutting out the specified HTML fragment and giving that to the requesting X11 app.
But Wine doesn't fully/correctly support importing text/html from X11 apps, as it uses the generic X11DRV_CLIPBOARD_ImportClipboardData() function, which simply provides the data as given by the X11 app. This won't have the expected headers that Windows apps want to see, so importing will usually fail. Even if apps can deal with the absence of headers, Firefox uses UTF-16, while apps expect UTF-8. Even if this weren't a problem, Windows apps expect the full HTML document and a fragment within it, while Firefox only provides the fragment.
We could disable importing text/html in Wine, which would make Windows apps request plain text types instead and succeed, or fix importing text/html. The current behaviour is a bad mixture of unimplemented and broken behaviour.
