-.SH DESCRIPTION
-These routines examine and operate on Unicode characters,
-in particular a subset of their properties as defined in the Unicode standard.
-Unicode defines some characters as alphabetic and specifies three cases:
-upper, lower, and title.
-Analogously to
-.IR ctype (3)

-.SM ASCII\c
-,
-these routines
-test types and modify cases for Unicode characters.
-The names are self-explanatory.
-.PP
-The case-conversion routines return the character unchanged if it has no case.

-.SH DESCRIPTION
-These routines convert to and from a
-.SM UTF
-byte stream and runes.
-.PP
-.I Runetochar
-copies one rune at
-.I r
-to at most
-.B UTFmax
-bytes starting at
-.I s
-and returns the number of bytes copied.
-.BR UTFmax ,
-defined as
-.B 3
-in
-.BR <libc.h> ,
-is the maximum number of bytes required to represent a rune.
-.PP
-.I Chartorune
-copies at most
-.B UTFmax
-bytes starting at
-.I s
-to one rune at
-.I r
-and returns the number of bytes copied.
-If the input is not exactly in
-.SM UTF
-format,
-.I chartorune
-will convert to 0x80 and return 1.
-.PP
-.I Runelen
-returns the number of bytes
-required to convert
-.I r
-into
-.SM UTF.
-.PP
-.I Runenlen
-returns the number of bytes
-required to convert the
-.I n
-runes pointed to by
-.I r
-into
-.SM UTF.
-.PP
-.I Fullrune
-returns 1 if the string
-.I s
-of length
-.I n
-is long enough to be decoded by
-.I chartorune
-and 0 otherwise.
-This does not guarantee that the string
-contains a legal
-.SM UTF
-encoding.
-This routine is used by programs that
-obtain input a byte at
-a time and need to know when a full rune
-has arrived.
-.PP
-The following routines are analogous to the
-corresponding string routines with
-.B utf
-substituted for
-.B str
-and
-.B rune
-substituted for
-.BR chr .
-.PP
-.I Utfecpy
-copies UTF sequences until a null sequence has been copied, but writes no 
-sequences beyond
-.IR es1 .
-If any sequences are copied,
-.I s1
-is terminated by a null sequence, and a pointer to that sequence is returned.
-Otherwise, the original
-.I s1
-is returned.
-.PP
-.I Utflen
-returns the number of runes that
-are represented by the
-.SM UTF
-string
-.IR s .
-.PP
-.I Utfnlen
-returns the number of complete runes that
-are represented by the first
-.I n
-bytes of
-.SM UTF
-string
-.IR s .
-If the last few bytes of the string contain an incompletely coded rune,
-.I utfnlen
-will not count them; in this way, it differs from
-.IR utflen ,
-which includes every byte of the string.
-.PP
-.I Utfrune
-.RI ( utfrrune )
-returns a pointer to the first (last)
-occurrence of rune
-.I c
-in the
-.SM UTF
-string
-.IR s ,
-or 0 if
-.I c
-does not occur in the string.
-The NUL byte terminating a string is considered to
-be part of the string
-.IR s .
-.PP
-.I Utfutf
-returns a pointer to the first occurrence of
-the
-.SM UTF
-string
-.I s2
-as a
-.SM UTF
-substring of
-.IR s1 ,
-or 0 if there is none.
-If
-.I s2
-is the null string,
-.I utfutf
-returns
-.IR s1 .
-.SH HISTORY
-These routines were written by Rob Pike and Ken Thompson
-and first appeared in Plan 9.
-.SH SEE ALSO
-.IR utf (7),
-.IR tcs (1)

-.SH DESCRIPTION
-These functions are rune string analogues of
-the corresponding functions in 
-.IR strcat (3).
-.SH HISTORY
-These routines first appeared in Plan 9.
-.SH SEE ALSO
-.IR memmove (3),
-.IR rune (3),
-.IR strcat (2)
-.SH BUGS
-The outcome of overlapping moves varies among implementations.

-.TH UTF 7
-.SH NAME
-UTF, Unicode, ASCII, rune \- character set and format
-.SH DESCRIPTION
-The Plan 9 character set and representation are
-based on the Unicode Standard and on the ISO multibyte
-.SM UTF-8
-encoding (Universal Character
-Set Transformation Format, 8 bits wide).
-The Unicode Standard represents its characters in 16
-bits;
-.SM UTF-8
-represents such
-values in an 8-bit byte stream.
-Throughout this manual,
-.SM UTF-8
-is shortened to
-.SM UTF.
-.PP
-In Plan 9, a
-.I rune
-is a 16-bit quantity representing a Unicode character.
-Internally, programs may store characters as runes.
-However, any external manifestation of textual information,
-in files or at the interface between programs, uses a
-machine-independent, byte-stream encoding called
-.SM UTF.
-.PP
-.SM UTF
-is designed so the 7-bit
-.SM ASCII
-set (values hexadecimal 00 to 7F),
-appear only as themselves
-in the encoding.
-Runes with values above 7F appear as sequences of two or more
-bytes with values only from 80 to FF.
-.PP
-The
-.SM UTF
-encoding of the Unicode Standard is backward compatible with
-.SM ASCII\c
-:
-programs presented only with
-.SM ASCII
-work on Plan 9
-even if not written to deal with
-.SM UTF,
-as do
-programs that deal with uninterpreted byte streams.
-However, programs that perform semantic processing on
-.SM ASCII
-graphic
-characters must convert from
-.SM UTF
-to runes
-in order to work properly with non-\c
-.SM ASCII
-input.
-See
-.IR rune (2).
-.PP
-Letting numbers be binary,
-a rune x is converted to a multibyte
-.SM UTF
-sequence
-as follows:
-.PP
-01.   x in [00000000.0bbbbbbb] → 0bbbbbbb
-.br
-10.   x in [00000bbb.bbbbbbbb] → 110bbbbb, 10bbbbbb
-.br
-11.   x in [bbbbbbbb.bbbbbbbb] → 1110bbbb, 10bbbbbb, 10bbbbbb
-.br
-.PP
-Conversion 01 provides a one-byte sequence that spans the
-.SM ASCII
-character set in a compatible way.
-Conversions 10 and 11 represent higher-valued characters
-as sequences of two or three bytes with the high bit set.
-Plan 9 does not support the 4, 5, and 6 byte sequences proposed by X-Open.
-When there are multiple ways to encode a value, for example rune 0,
-the shortest encoding is used.
-.PP
-In the inverse mapping,
-any sequence except those described above
-is incorrect and is converted to rune hexadecimal 0080.

-.IR tcs (1),
