Summary [Qt] copy and paste greek symbols to Word, TextEdit results in ?'s being shown

This bug report originated from issue QTBUG-8429 http://bugreports.qt.nokia.com/browse/QTBUG-8429 --- Description --- I'm not sure if this is a Qt or a webkit issue, and there is a Qt twist, so I'm posting it here: <p>-create an editable QWebView<br/> -insert some greek letters (e.g. αβγδεζηθικλμπ)<br/> -select them<br/> -do a Copy<br/> -open up Word or TextEdit.app and paste</p> <p>You get ?'s, instead of the greek letters. Strangly other editors, like QtCreator and Smultron have no trouble displaying them.</p> <p>Theory: the data is on the clipboard just fine, but the encoding is not being included.</p> <p>I found a hacky workaround: use QClipboard to push the data back on again like so:</p> <p> //something is goofy with the encoding, so copy again using QClipboard directly...<br/> qApp-&gt;clipboard()<del>&gt;setText( qApp</del>&gt;clipboard()-&gt;text() );</p> <p>This actually works, but in order to trap a slew of copy calls you have to do stuff like reimplement QWebView's keyPressEvent function.</p>

This is caused by Pasteboard::writeSelection() calling QMimeData::setHtml() and there's two separate issues involved here. 1) QMacPasteboardMimeAny::convertFromMime() returns UTF-8 data only for text/plain, not text/html. Not sure if this is intended or not but I don't think it can be changed in Qt without breaking existing code. 2) HTML on the Pasteboard on OS X needs to be explicitly told that it contains unicode data (i.e. using a <meta> tag). I'll upload a patch shortly that fixes this.

Comment on attachment 76329 [details] Patch Seems you'd want to share more code with PasteboardMac here. :(

Comment on attachment 76329 [details] Patch We really need a better way of testing clipboard tests like this.

(In reply to comment #5) > (From update of attachment 76329 [details]) > We really need a better way of testing clipboard tests like this. Agreed. This particular one would be hard to test though since this bug only happens when copying from QtWebKit and pasting to a non-Qt program so I don't see how this could be tested without launching an external application.

Created attachment 77245 [details] Patch Change the manual test case in the previous test to an autotest for Qt which checks that QClipboard contains the selected unicode data and also verifies that the clipboard data contains the charset information

> Seems you'd want to share more code with PasteboardMac here. :( This bug is caused by Qt-specific handling in its QClipboard abstraction.
