Supports four methods for every class:

• encode — encodes, replacing characters to its entity representations. Ignores UTF characters with no entity representation.
• encodeNonUTF — encodes, replacing characters to its entity representations. Inserts numeric entities for UTF characters.
• encodeNonASCII — encodes, replacing only non-ASCII characters to its numeric entity representations.
• decode — decodes, replacing entities to characters. Unknown entities are left as is.
