Once upon a time the used to be computers speaking ASCII or EBCDIC. The
ASCII computers where unix mostly. The EBCDIC where mainframes. ASCII
mode meant that EBCDIC card decks with fixed lenght of mostly 80 characters
per line would be translated into variable lenght records terminated by
CR/LF before sending them. Also they would be translated from 8 bit
EBCDIC code to 7 bit ASCII code. Unix would have to replace their single
LF character by a CR/LF sequence before sending. The result could be
punched to 7 bit punched tapes automatically adding a parity bit to the
tape. Or you could print it directly on an ASR-33 terminal.
Binary means take it as it is. Dont touch the formatting or character
set.
As the ASR-33 terminal did not know UTF-8 it is not a good idea to use
ASCII mode for UTF-8. But you can send it only to systems who understand
UTF-8.

Hi,
RFC 959, says that FTP supports two modes to transfer files -- ASCII and
Binary. Now, if I have a UTF-8 (or any other encoding) encoded text
file, containing, say Japanese characters, would it be correct to choose
the transfer mode as ASCII? And if I choose the transfer mode as ASCII,
is there a possibility that the content of the file on the receiving end
is garbled?
In a nutshell, does ASCII mode means that only ASCII encoded text files
are supported?
Thanks,
Sandeep.
