-  uses the US-ASCII 7-bit character set, and treats bytes with the high bit set
-  as invalid characters. That's why, e.g., the <command>ls</command> command
-  substitutes them with question marks in that locale. Also, an attempt to send
-  mail with such characters from Mutt or Pine results in non-RFC-conforming
-  messages being set (the charset in the outgoing mail is indicatsed as "unknown
-  8-bit"). So you can use the <quote>C</quote> locale only if you are sure that

-  <para>UTF-8 based locales are not supported well by many programs. E.g., the

-  locales and has no such restriction in traditional 8-bit locales like en_US.
-  Without patches and/or installing software beyond BLFS, in UTF-8 based locales
-  you will not be able to do such basic tasks as printing plain-text files from
-  the command line, recording Windows-readable CDs with filenames containing
-  non-ASCII characters, viewing ID3v1 tags in MP3 files and so on. It is also
-  impossible (without damaging non-ASCII characters) to connect using ssh from
-  the system using a UTF-8 based locale to a host that still uses a traditional
-  8-bit locale, and vice versa. In short, use UTF-8 only if you are going to
-  use KDE or GNOME and never open the terminal, or if you are going to tolerate
-  bugs.</para>
