html2text function called indirectly from format_text_email function is not compatible with utf-8 charset encoding. html2text replaces all chr(160) bytes with ' ' at end of the function, while chr(160) in utf-8 encoding does not mean a white space. This causes some characters in utf-8 encoding such as 'da' (U+3060) characters in ja_utf8 garbled in text formatted email.
