    Not even in CDATA section? I wonder what characters those might be.

    https://www.w3.org/TR/REC-xml/#charsets

    Character Range
    [2] Char ::= #x9 | #xA | #xD | [#x20-#xD7FF] |
    [#xE000-#xFFFD] | [#x10000-#x10FFFF]
    /* any Unicode character, excluding the surrogate blocks, FFFE, and FFFF. */

    Most of the control characters are explicitly excluded, plus some
    unicode code points.

    And, yes, even in CDATA sections, because CDATA references the above
    "Char" definition to define what characters are allowed in CDATA:

    [20] CData ::= (Char* - (Char* ']]>' Char*))

    The one I encountered was chr(3), a.k.a. CTRL/C. Somehow one of the
    operators had managed to enter that into a comments field, causing my export-to-XML function to fail.
