Thank you.
If I use
gsub(" \xad", "-", x)
[1] "NEW YORK-NEW ENGLAND"
I get what I want.
Right, that's simpler than what I suggested.

So they are different.
We really do need the 'at a minimum' information we asked you for in the
posting guide. But in cp1252 (a guess as to what you might be using) \xad is
a 'soft hyphen', and that is not the same thing as a hyphen -- you will get
the same issues with 'non-breaking space'.

Hello,
Below is some output that shows my issue.
I have a variable x that I read from a file (more on this below)
x
[1] "NEW YORK NEW ENGLAND"
gsub(" -", "-", x) # this does not work!
[1] "NEW YORK NEW ENGLAND"
Well, I see no hyphen at all here, but then I am not on Windows.
It looks as though it worked, presumably because something got lost in
your email.
Could you post charToRaw(x) so we can see what's in x?
Duncan Murdoch
Encoding(x) # is x in a special encoding? no
[1] "unknown"
y = "NEW YORK -NEW ENGLAND" # I type in variable y
gsub(" -", "-", y) # and gsub works as expected
[1] "NEW YORK-NEW ENGLAND"
I'm sure the problem has to do with the way I read the variable x. But
even if I change the encoding for x to ASCII, I still cannot do the sub.
I get x by reading a pdf file with pdftotext so you will not be able to
replicate my issue.
Thanks for any suggestions,
Adrian
