UTF          {UCS transformation format}
From The Free On-line Dictionary of Computing (15Feb98) [foldoc]:
UTF-8          (UCS transformation format 8) An       {ASCII}-compatible multibyte {Unicode} and {UCS} encoding,       used by {Java} and {Plan 9}.          The {Unicode character} set occupies a 16-bit code space.   The       most obvious Unicode encoding (known as UCS-2) consists of a       sequence of 16-bit words.   Such strings can contain bytes like       '\0' or '/' which have a special meaning in filenames and       other {C} library function parameters.   In addition, the       majority of {Unix} tools expects ASCII files and can't read       16-bit words as characters without major modifications.   For       these reasons, UCS-2 is not a suitable external encoding of       Unicode in filenames, text files, environment variables, etc.          The {ISO 10646} {Universal Character Set} (UCS), a superset of       Unicode, occupies a 31-bit code space and the obvious UCS-4       encoding for it (a sequence of 32-bit words) has the same       problems.          The UTF-8 encoding of Unicode and UCS avoids the problems of       fixed-length Unicode encodings because an ASCII file encoded       in UTF is exactly same as the original ASCII file and all       non-ASCII characters are guaranteed to have the most       significant bit set (bit 0x80).   This means that normal tools       for text searching etc. work as expected.          UTF-8 is defined in {RFC 2279}.          ["File System Safe UCS Transformation Format (FSS_UTF)",       X/Open Preliminary Specification, X/Open Company Ltd.,       Document Number: P316.   This information also appears in       ISO/IEC 10646, Annex P].          {Plan 9 UTF manual entry       (ftp://ftp.uu.net/doc/obi/Bell.Labs/plan9pm/09utf.ps.Z)}.          (1998-07-29)
