The logic is in src/library/tools/R/QC.R (.check_package_code_syntax). 
If I read correctly, the underlying reason could be that you have 
"Encoding: latin1" in DESCRIPTION.

For a workaround, you could play with the R_ENCODING_LOCALES environment 
variable (documented in R-exts), but I suspect it is easier just to 
install en_US.
