[R-pkg-devel] ASCII code for Degree symbol °

[Rafael H. M. Pereira]

Hi all.

In one of the functions of my package (flightsbr), I have a vector with
character strings where I need to replace the degree symbol ° with a point
'.' So this is what I do:

vec <- gsub("[°]", ".", vec)

However, I keep getting this Warning from devtools::check():
  Found the following file with non-ASCII characters:
    utils.R
  Portable packages must use only ASCII characters in their R code,
  except perhaps in comments.
  Use \uxxxx escapes for other characters.

I assume there is a ASCII representation of °, but I cannot really find a
way to do this using ASCII  characters. Any ideas?

best,
Rafael Pereira
