 Requirements
 ------------
 
-- C11 or C++17.
+- C99 (at least `EILSEQ` has to be available as errno constant).
+- C11 (for running tests).
 
 Installation (C++ variant)
 --------------------------
 
 Just copy the files unicode.cpp and unicode.hpp and add them to your project.
 
-Installation (C variant)
-------------------------
+Installation
+------------
 
-Copy the files unicode.c and unicode.h and add them to your project.
+Copy unicode.h and unicode.c to your project.
 
 Regeneration
 ------------
 
-The file unicode.c and unicode.cpp are generated from gen/ subdirectory. Edit
-the appropriate files and run `make` in top level directory to regenerate them.

 Introduction
 ------------
 
-Conversions and unicode inspection in C++17 or C11.
+Conversions and unicode inspection in C99
 
 It is currently based on unicode 13.0.0.
 
+Features
+--------
+
+- UTF-8 encoding/decoding back-and-forth to UTF-32,
+- no dynamic allocation required,
+- only C99 required.
+- less than 250 lines of code (excluding code generation).
+
 Documentation
 -------------
 
-See functions defined in unicode.hpp and unicode.h
+See the libunicode(3) manual page.
+
+	man ./libunicode.3

- * make is(upper|lower|title|space|alpha)rune and

- *
- * with -c, runs a check of the existing runetype functions vs.
- * those extracted from UnicodeData.
- *
- * with -p, generates tables for pairs of chars, as well as for ranges

- *
- * UnicodeData defines 4 fields of interest:
- * 1) a category
- * 2) an upper case mapping
- * 3) a lower case mapping
- * 4) a title case mapping
- *
- * toupper, tolower, and totitle are defined directly from the mapping.
- *
- * isalpharune(c) is true iff c is a "letter" category
- * isupperrune(c) is true iff c is the target of toupperrune,
- *  or is in the uppercase letter category
- * similarly for islowerrune and istitlerune.
- * isspacerune is true for space category chars, "C" locale white space chars,
- *  and two additions:
- *  0085    "next line" control char
- *  feff]   "zero-width non-break space"
- * isdigitrune is true iff c is a numeric-digit category.

+.\" DESCRIPTION
+.Sh DESCRIPTION
+This set of functions allows back-and-forth conversions between UTF-8 and
+UTF-32 character sets. All input strings (both UTF-8 and UTF-32) are considered
+to be NUL-terminated when use as input. Output strings are always NUL terminated
+unless specified otherwise.
+.Pp
+Functions prefixed with
+.Dq uni8_
+are referring to UTF-8 source or destination.
+.Pp
+Functions prefixed with
+.Dq uni32_
+are analogous to their respective
+.Dq uni8_
+counterparts if applicable.
+.Pp
+Finally, generic functions prefixed with
+.Dq uni_
+do not perform any conversion and are made for character class classificiation.
+.Pp
+The
+.Fn uni8_encode
+function transforms the unicode character
+.Fa point
+and store the result as UTF-8 string into
+.Fa dst
+of
+.Fa dstsz
+bytes long. The output string is
+.Em not
+NUL terminated and must be at least 4 bytes long, otherwise it may be truncated.
+.Pp
+The
+.Fn uni8_decode
+function reads the UTF-8 NUL-terminated
+.Fa src
+input string and converts the result into
+.Fa point
+as unicode character.
+.Pp
+The
+.Fn uni8_sizeof
+function returns the number of bytes that are following the byte
+.Fa c
+in a multibytes sequence. It can be used while iterating a UTF-8 string to jump
+a specific number of bytes while encountering a multibytes sequence.
+.Pp
+The
+.Fn uni8_length
+function returns the number of unicode characters (which is lesser or equal of
+the number of bytes) in the UTF-8 NUL terminated
+.Fa src
+string.
+.Pp
+The
+.Fn uni8_to32
+function converts the UTF-8
+.Fa src
+input string into the
+.Fa dst
+array of
+.Fa dstsz
+bytes long. The function writes at most
+.Fa dstsz
+bytes including the NUL terminator character, make sure to reserve an additional
+space for it before calling this function.
+.Pp
+The
+.Fn uni32_sizeof
+function returns the number of UTF-8 characters required to convert the unicode
+.Fa point
+character to UTF-8.
+.Pp
+The
+.Fn uni32_length
+function returns the number of unicode characters present in the UTF-32 NUL
+terminated
+.Fa src
+string.
+.Pp
+The
+.Fn uni32_requires
+function computes the total number of bytes (excluding the NUL terminator) that
+are required to build a UTF-8 string from the UTF-32 NUL terminated
+.Fa src
+string.
+.Pp
+The
+.Fn uni32_to8
+function converts the UTF-32 NUL terminated
+.Fa src
+string and stores the result as UTF-8 in
+.Fa dst
+of
+.Fa dstsz
+bytes long. The function writes at most
+.Fa dstsz
+bytes including the NUL terminator character, make sure to reserve an additional
+space for it before calling this function.
+.Pp
+The
+.Fn uni_isalpha
+returns non-zero if the the unicode character
+.Fa point
+is considered alphanumeric class.
+.Pp
+The
+.Fn uni_isdigit
+returns non-zero if the the unicode character
+.Fa point
+is considered numeric class.
+.Pp
+The
+.Fn uni_islower
+returns non-zero if the the unicode character
+.Fa point
+is considered lower case class.
+.Pp
+The
+.Fn uni_istitle
+returns non-zero if the the unicode character
+.Fa point
+is considered title case class.
+.Pp
+The
+.Fn uni_isupper
+returns non-zero if the the unicode character
+.Fa point
+is considered upper case class.
+.Pp
+The
+.Fn uni_toupper
+returns the upper case variant of the unicode character
+.Fa point .
+.Pp
+The
+.Fn uni_tolower
+returns the lower case variant of the unicode character
+.Fa point .
+.Pp
+The
+.Fn uni_totitle
+returns the title case variant of the unicode character
+.Fa point .
+.\" RETURN VALUES
+.Sh RETURN VALUES
+The
+.Fn uni8_encode ,
+.Fn uni8_to32
+and
+.Fn uni32_to8
+functions return the number of bytes written (excluding NUL terminator) into
+.Fa dst
+or -1 in case of error.
+.Pp
+The
+.Fn uni8_decode
+function returns the number of bytes parsed from
+.Fa src
+string or -1 in case of error.
+.Pp
+The
+.Fn uni8_sizeof
+and
+.Fn uni8_length
+functions return -1 in case of error.
+.Pp
+The
+.Fn uni32_sizeof
+and
+.Fn uni32_requires
+functions return -1 in case of error.
+.\" ERRORS
+.Sh ERRORS
+The global
+.Va errno
+variable can be set in case of error using the following macro constants:
+.Bl -tag -width Er
+.It Bq Er EILSEQ
+When an invalid sequence was found. Can be set in
+.Fn uni8_decode ,
+.Fn uni8_sizeof ,
+.Fn uni8_length ,
+.Fn uni8_to32 ,
+.Fn uni32_sizeof ,
+.Fn uni32_requires
+and
+.Fn uni32_to8 .
+.It Bq Er ERANGE
+Set when there wasn't enough room to store conversion. Can be set in
+.Fn uni8_encode ,
+.Fn uni8_to32 ,
+.Fn uni32_requires
+and
