Convert character set: Conversion between many character set encodings

This class is meant to convert text strings between different character set encodings. These are the main features of the class:

- Conversion between 1 byte character sets
- Conversion from 1 byte to multi byte character set (utf-8)
- Conversion from multibyte character set (utf-8) to 1 byte character set
- Every conversion output can be save with numeric entities (browser character set independent)

This is a list of character sets you can operate with. The main requirement is that a character has to be in both character sets, otherwise it will return an error.
