I like your examples, Richard, of strings that should not be considered as
numbers. There are times you want to recognize something like "221B Baker
Street" and extract the 221 or perhaps the 221B as a part of a full address and
ignore the rest. But one goal of a function like as.numeric() is to
This is not for the R inferno.
This is for the Microsoft interno, or perhaps the Unicode inferno.
The Byte Order Mark is supposed to appear at the beginning of UTF-32
or UTF-16 *external* data, like a file
or data coming over a socket.
In the Microsoft world, it also tends to appear at the beginnin
The zero-width no-break space character is used as the Byte Order

is to indicate whether you have 2-byte or 4-byte big-endian or
little-endian encoding. It was not intended for use in UTF-8, where
there is nothing
This issue looks like grist for the R Inferno.

from a text-processing environment where it was going to wrap there and was
protected?
Thanks all for your responses. My problem is solved.
