We got special characters available via the Mac OS X system fonts, why not use them on mailbox folder? Using the Character Viewer menu item, we can quickly browse all these icons and insert them into any working document. This includes mailbox names in Mail. This should work in other mail clients as well.
Here’s a quick visual guide to pimping folders in Mail.
Step 1: Enable the Character Viewer menu item.
Select Language and Text in your System Preferences. This is found under the apple menu.
Under the Input Sources, select Keyboard & Character Viewer. This will enable the pull down menu item in your main menu.
Step 2: Look up and insert character.
In your Mail application, select the mailbox in place with one click to go into edit mode.
From your to main menu, Select Show Character Viewer from Character & Keyboard menu item.
Browse the available Symbols and find the one you want. Double clicking it will place the character in the Mail app.
