Property charset : WideString; (Read/Write)
An Internet Assigned Numbers Authority (IANA) Charset Registered character set and character encoding for character-based encoding types.
Whenever the content of the ED is character type data in any form, the charset property needs to be known. If the content is provided directly in the value attribute, then the charset SHALL be a known character set consistent with the String Character Set. Refer to section 6.7.5 for more details. If the content is provided as a reference, and the access method does not provide the charset for the content (such as by a mime header), then the charset SHALL be conveyed as part of the ED
