Formula book fails to insert power operation

[Pol Welter]

In the current version there seems to be a bug when trying to insert a formula with a power operation. Instead of inserting ^, it displays %5e2. Try for example the quadratic equation, or any of the electrical power formulas.

I built SpeedCrunch master (as of Aug 26 2015) using QT 5.4 and MinGW.

FWIW, this issue seems related to Qt5 builds because it does not appear when built with Qt4.8.7. I can confirm it happens with Qt5.5.0 when built with MinGW, but I don't know if it happens also on Linux.

Can you try the attached patch with Qt5.4 please? I know it fixes this issue for Qt5.5, but I have the feeling it uses a flag which is not defined in previous Qt5 versions.

Note that this is not a git patch, so git might not like it (but the changes are easy to do manually anyway).

The cause of the issue is that the QUrl::toString() behaviour has changed since Qt4, and it does not decode some percent-encoded characters now (and the ^ character is encoded that way in the formula book).

[Pol Welter]

I confirm that Tey's patch works with Qt 5.4.

Thanks for the confirmation Pol. The QUrl::DecodeReserved flag seems to exist since Qt5.3 at least, so I guess it's okay.

@HelderCorreia: I'm the assignee but it does not give me any control over this issue, so close it when the PR is accepted please.

@Teyut I just gave you Write permissions, you should be able to modify issues now, I believe.

@heldercorreia: indeed, I see the controls now. Thanks.

Applied Tey's patch for fixing issue #571
