If I undestand the CRAN package check results correctly, the problem seems to be some characters, that are not translated by the package inputenc in the CRAN server:

U+2010 is the hyphen character.  It looks a lot like the ascii "-" (code 
2D), which Unicode calls "hyphen-minus".

You can find occurrences of it (and other non-ASCII chars) in your files 
using the tools::showNonASCIIfile() function, e.g.

   files <- list.files(recursive = TRUE)
   for (f in files) tools::showNonASCIIfile(f)
