Fix EZP-26748: Wrong image URI when content name has extended UTF characters

[glye]

Fixes https://jira.ez.no/browse/EZP-26748
Test in https://github.com/ezsystems/ezpublish-kernel-ee/pull/145
Taken from https://github.com/ezsystems/ezpublish-platform/pull/20 where the tests don't run
Status: Ready to merge

Fixes the problem by ensuring UTF-8 is used, though this probably isn't the ideal way to do it. Anyway, let's see how the full tests go.

Review ping @andrerom @bdunogier - this is a (perhaps too) simple solution. I have hardcoded it because AFAIK ezp is utf-8 only.

[bdunogier]

I'm not a charset expert, but based on what I know it looks okay.

Do we need to add the same thing to our tests bootstrap files, to be consistent ?

@bdunogier Sounds good. Could you give some pointers? (Travis/Behat config?)

[bdunogier]

For phpunit, it would probably be in bootstrap.php. Behat will be taken care of by the change you've done here, as it uses app.php.

Ok, that would be bootstrap.php in kernel, repoforms, pui and other repos, then?

[andrerom]

Bootstrap is one thing, we also more importantly need to add this in app/console, right?

Update: Added same in app/console, thanks.
Wondering to what degree console commands are tested here. Locally at least cache clear seems fine with the change. (In most cases it doesn't matter, anyway.)

Don't forget to send it to QA 😄
