	Other than EBCDIC, <lf> and <cr> AS BYTES should appear as x0A and x0D
in any of the 8-bit encodings (ASCII, ISO-8859-x, CPxxxx, UTF-8). I believe
those bytes also appear in UTF-16 -- BUT, they will have a null (x00) byte
associated with them as padding; as a result, you can not search for just
x0Dx0A (Windows line end convention -- they may be x00x0Dx00x0A or
x0Dx00x0Ax00 depending on endianness cf:
https://docs.microsoft.com/en-us/cpp/text/support-for-unicode?view=msvc-170
)

	For EBCDIC <cr> is still x0D, but <lf> is x25 (and there is a separate
<nl> [new line] at x15)
