It's a matter of parallel evolution. File systems like your MTS example
("Bright college days, oh, carefree days that fly..." -- Tom Lehrer)
were born on mainframe systems that had lots of buffering capability and
processing power. ASCII text files were born on Teletype networks which
had very little processing capability and even less buffering. Given the
constraints of the time, I'd say that each system served its purposes well.
ASCII text files are so much simpler that their limitations are often not
a serious factor - e.g., when transmitting text.
That DLE character mentioned upthread stands for "Data Link Escape",
and it shows that the designers of those Teletype networks were
thinking about the problem.
