As pointed out in my other e-mail, "everywhere necessary" implies either
"dear user, convert all your files from the original encoding before you
want programs created in FPC to touch them" or "dear programmer targetting
OS/370, make sure that your programs are limited in what RTL functions you
use, or convert all locally stored files to ASCII and only use the RTL
functions for text processing on the converted copies". Otherwise even
stuff like line by line reading or field by field reading of the input
text file using standard RTL routines may not work as expected with the
current RTL.
