1) If text/* proves to be problematic, why not use application/*?

2) Also, keep in mind that while RFC2046 may be interpreted not to 
mandate the ASCII default for text types other than text/plain, there's 
also RFC2616 saying...:

    The "charset" parameter is used with some media types to define the
    character set (section 3.4) of the data. When no explicit charset
    parameter is provided by the sender, media subtypes of the "text"
    type are defined to have a default charset value of "ISO-8859-1" when
    received via HTTP. Data in character sets other than "ISO-8859-1" or
    its subsets MUST be labeled with an appropriate charset value. See
    section 3.4.1 for compatibility problems. --
