Arabic-friendly Exeption reporting in Slim Framework 2 & 3

Today I've been upgrading my Slim PHP project from version 2 to version to version 3 beta. And one of the issues I had was reporting my Arabic exceptions from some models I have. I did this before in version 2, to end up with moving from this scrambled message:

to this one:

In Slim Framework 2, I had to edit Middleware / PrettyExceptions.php to add a meta tag for content UTF-8 encoding:

<meta http-equiv='Content-Type' content='text/html; charset=utf-8'>

Now, when I moved to Slim Framework 3.0.0-beta2, I had to do this again but in Handlers/Error.php.

I hope that this trick helps someone on the planet. And I think I may create a pull request for this small hack.

Update: pull request has been merged. (#1470)

[Node JS] Test specific files with Mocha

This is a handy command line I use for testing specific files while developing a certain module for a faster test. I just call Mocha, (optionally) specify my preferred terminal reporter, then I call the files to go through:

mocha --reporter spec ./test/modules/abc.js ./test/modules/def.js

That's it. It is that simple. This way I can run tests on specific files and save some time.
