I've just submitted a new plugin called Character Browser.
This plugin allows you to browse the Unicode character set. The character set is organized into various groupings to help make it easier to find the character you need. Search capabilities also allow you to find characters by code or name using regular expressions.
You can insert a character into the current editor in one of ten forms:
- Character Code in hex, decimal, and octal
- Unicode Code Point
- Character Name
- Java Unicode Escape
- Java Octal Character Escape
- HTML Named Entity
- HTML Decimal Entity
