        <pre>Example in cell A1 containing an ASCII 10 newline (Ctrl+Enter):

    1
    2

This works as a spreadsheet formula but not in Data > Validity > Custom,
Formula.

    =NOT(ISERROR(SEARCH(CHAR(10);A1)))

Expected Result:

    Cell A1 should be accepted as valid.

Actual Result:

    Invalid value.

On further investigation, the following formula passes validity, so it seems
that newlines are handled to some extent.

    NOT(ISERROR(SEARCH(CHAR(10);"1" & CHAR(10) & "2")))
