Well, form feed (control-L) is an ASCII character and part of the
standard character set, but I'm quite surprised to hear that it's a
logical-end-of line, for two reasons:

  - If anything, it's-end-of page, not-end-of line.

  - And it's not even that.  The RM in A.10(8) is quite clear that the
    standard does not specify which characters, if any, correspond to
    logical end-of-line or end-of-page or end-of-file.

I'll agree that many implementations, probably most of them, choose to
implement end-of-page using the ASCII form feed character, but the
standard is silent on the subject.
