I am not certain how to interpret the following:
"The default file encoding will be ISO-Latin-1 in R16,
but will be changed to UTF-8 in R17.

Source code will need no change in R16, but adding a
comment denoting ISO-Latin-1 encoding will ensure that
the code can be compiled with the R17 compiler."

Will we have to add an encoding comment for unmodified
source code in R17 (that is pure 7-bit ASCII)?
