PyCharm can create it's own launcher icon (but it's not created by default).
All you have to do is:
- Start PyCharm.
- From the Tools menu, select "Create Desktop Entry..."
- Tick the corresponding box if you want the launcher for all users.
- If you selected "Create entry for all users", you will be asked for your password.
- A green message bubble should appear informing you that it was successful.
- You should then be able to find PyCharm in the Unity Dash or pin it to the launcher.
Note: You may need a system restart before it appears.
