How can I post array keys that have special charachters? : I have a form that contains some special characters as the keys. 
 Below is an example:

  <input type="text" name="skills[React.js]" placeholder="Years" class="form-control">
<input type="text" name="skills[Responsive-Web-Design-(RWD)]" placeholder="Years" class="form-control">

When I post the form I get 0:value, 1:value
Instead of React.js:value, Responsive-Web-Design-(RWD): value

Does anyone might know any workarounds? 

Any help would be really appreciated!
