-// First: single-byte-coded (SBC) character sets:
-
-// 7-bit ASCII is a subset of the various ISO/IEC 8859 code pages.
-// 8859 is a subset of code page 1252.
-// CP1252 is informally, and improperly, known as the "ANSI" code set. In
-// modern usage, when somebody says "8859-1", they almost invariably are
-// referring to a CP1252 code set.
-
-// EBCDIC is also an SBC character set. IBM's original "international EBCDIC"
-// code set was Code Page 37, which did not have a Euro sign. Code Page 1140
-// is the same as CP37, but with the Euro sign replacing the "universal
-// currency symbol" at position 0x9F. The table below maps the 256 values of
-// CodePage 1140 to the 256 values of CodePage 1252 in a way that allows for
-// "round trip" conversion without any loss.
-
-// See https://en.wikipedia.org/w/index.php?title=Code_page_37&oldid=1082467670,
-
-// The modern world increasingly uses UTF-8, which is in conflict with ordinary
-// COBOL's inherently single-byte nature. In UTF-8, the encoding for a Euro
-// sign is three bytes (U+20AC encodes to E2 A2 AC). In single-byte CP1252, the
-// Euro is encoded as 0x80.
-
-// So, we are going to assume that internally, the generated COBOL executable
-// operates in code page 1252 or [hopefully some day] code page 1140.
-
-// We will convert output, as in DISPLAY <something> from the internal character
-// set to the running machine's locale (for now, that locale will be assumed to
-// be 1252/8859 if it isn't UTF-8).
-
-// And we will take some pains to figure out if the source code file was done
-// as UTF-8; if not, we will assume 1252/8859-1
