+++ This bug was initially created as a clone of Bug #1591268 +++ Converting files or characters using iconv (or the iconv library) result in an "illegal input sequence" error when encountering an "overscore" character (IS08859-1: Hex "AF"). This happens tough there is a corresponding character is available in IBM273 (Hex: "BC"). Converting to IBM1141, which is the same table as IBM273 except for the EURO-Sign works. You can reproduce this behavior with the following command: echo "AF" | xxd -r -p | iconv -f iso8859-1 -t ibm273 In contrast: echo "AF" | xxd -r -p | iconv -f iso8859-1 -t ibm1141 works. Using ibm273//TRANSLIT is not an option currently, as it would require a lot of changes in the user code, and would just not throw an error, but replace the "overscore" with an "o". This problem happens in rhel7 and fedora 28.
