UI fails if text contains {...}

[sclause2412]

Problem

If the text contains curly braces the interface fails because it tries to replace it with a route parameter.

How to reproduce

Make any translation containing curly braces like: `__('Use {red} to make the text red.')
Then import the translations. This will generate a line in the table containing the key "Use {red} to make the text red." which is fine at this point.
When now accessing the interface it fails with this message:

Illuminate \ Routing \ Exceptions \ UrlGenerationException
Missing required parameter for [Route: ] [URI: translations/delete/{groupKey}/{translationKey}] [Missing parameter: red].

The reason is that the function "action" gets the key as parameter without checking the content.

Solution

In the view file (resources/views/index.php) change the line

<a href="<?php echo action('\Barryvdh\TranslationManager\Controller@postDelete', [$group, $key]) ?>"

to

<a href="<?php echo action('\Barryvdh\TranslationManager\Controller@postDelete', [$group, urlencode($key)]) ?>"

and in the controller file (src/Controller.php) change the line

Translation::where('group', $group)->where('key', $key)->delete();

to

Translation::where('group', $group)->where('key', urldecode($key))->delete();
