.htaccess url rewriting when special character (&, #) presented in value

I want to use user friendly url instead fo dynamic url using .htaccess
But I am facing a problem because in the url I have value including special character (& and #).
Example: Account & Administration, C # Programming

So how can i rewrite them?

Here is my current dynamic url:
http://www.domain.com/result.php?subject=Account & Administration
http://www.domain.com/result.php?subject=C # Programming

I like to use these friendly url:
http://www.domain.com/skills/Account+&+Administration OR http://www.domain.com/skills/Account-&-Administration
http://www.domain.com/skills/C+#+Programming OR http://www.domain.com/skills/C-#-Programming


Currently I am using this .htaccess
Options +FollowSymLinks
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ^skills/([^_]*)$ result.php?subject=$1 [L]

It works except when there is a '&' or '#' sign included with the value.
When value contain '&' sign then it take first part of the value only like bellow;
http://www.domain.com/skills/Account
