<a name="glib-Unicode-Manipulation.description"></a><h2>Description</h2>
<p>
This section describes a number of functions for dealing with
Unicode characters and strings. There are analogues of the
traditional <code class="filename">ctype.h</code> character classification
and case conversion functions, UTF-8 analogues of some string utility
functions, functions to perform normalization, case conversion and
collation on UTF-8 strings and finally functions to convert between
the UTF-8, UTF-16 and UCS-4 encodings of Unicode.
</p>
<p>
The implementations of the Unicode functions in GLib are based
on the Unicode Character Data tables, which are available from
<a class="ulink" href="http://www.unicode.org/" target="_top">www.unicode.org</a>.
GLib 2.8 supports Unicode 4.0, GLib 2.10 supports Unicode 4.1,
GLib 2.12 supports Unicode 5.0, GLib 2.16.3 supports Unicode 5.1.

<p>
A type which can hold any UTF-32 or UCS-4 character code, also known
as a Unicode code point.
</p>
<p>
If you want to produce the UTF-8 representation of a <a class="link" href="glib-Unicode-Manipulation.html#gunichar" title="gunichar"><span class="type">gunichar</span></a>,
use <a class="link" href="glib-Unicode-Manipulation.html#g-ucs4-to-utf8" title="g_ucs4_to_utf8 ()"><code class="function">g_ucs4_to_utf8()</code></a>. See also <a class="link" href="glib-Unicode-Manipulation.html#g-utf8-to-ucs4" title="g_utf8_to_ucs4 ()"><code class="function">g_utf8_to_ucs4()</code></a> for the reverse process.
</p>
<p>
To print/scan values of this type as integer, use
<a class="link" href="glib-Miscellaneous-Macros.html#G-GINT32-MODIFIER:CAPS" title="G_GINT32_MODIFIER"><code class="literal">G_GINT32_MODIFIER</code></a> and/or <a class="link" href="glib-Miscellaneous-Macros.html#G-GUINT32-FORMAT:CAPS" title="G_GUINT32_FORMAT"><code class="literal">G_GUINT32_FORMAT</code></a>.
</p>
<p>
The notation to express a Unicode code point in running text is as a
hexadecimal number with four to six digits and uppercase letters, prefixed
by the string "U+". Leading zeros are omitted, unless the code point would
have fewer than four hexadecimal digits.
For example, "U+0041 LATIN CAPITAL LETTER A".
To print a code point in the U+-notation, use the format string
"U+<code class="literal">04</code>"G_GINT32_FORMAT"X".
To scan, use the format string "U+<code class="literal">06</code>"G_GINT32_FORMAT"X".

Converts from an integer character offset to a pointer to a position
within the string.
</p>
<p>
Since 2.10, this function allows to pass a negative <em class="parameter"><code>offset</code></em> to
step backwards. It is usually worth stepping backwards from the end
instead of forwards if <em class="parameter"><code>offset</code></em> is in the last fourth of the string,
since moving forward is about 3 times faster than moving backward.

<p>
This function doesn't abort when reaching the end of <em class="parameter"><code>str</code></em>. Therefore
you should be sure that <em class="parameter"><code>offset</code></em> is within string boundaries before
calling that function. Call <a class="link" href="glib-Unicode-Manipulation.html#g-utf8-strlen" title="g_utf8_strlen ()"><code class="function">g_utf8_strlen()</code></a> when unsure.
</p>
<p>
This limitation exists as this function is called frequently during
text rendering and therefore has to be as fast as possible.

Converts a string into a form that is independent of case. The
result will not correspond to any particular case, but can be
compared for equality or ordered with the results of calling
<a class="link" href="glib-Unicode-Manipulation.html#g-utf8-casefold" title="g_utf8_casefold ()"><code class="function">g_utf8_casefold()</code></a> on other strings.

<p>
Note that calling <a class="link" href="glib-Unicode-Manipulation.html#g-utf8-casefold" title="g_utf8_casefold ()"><code class="function">g_utf8_casefold()</code></a> followed by <a class="link" href="glib-Unicode-Manipulation.html#g-utf8-collate" title="g_utf8_collate ()"><code class="function">g_utf8_collate()</code></a> is
only an approximation to the correct linguistic case insensitive
ordering, though it is a fairly good one. Getting this exactly
right would require a more sophisticated collation function that
takes case sensitivity into account. GLib does not currently
provide such a function.

Converts a string into canonical form, standardizing
such issues as whether a character with an accent
is represented as a base character and combining
accent or as a single precomposed character. The
string has to be valid UTF-8, otherwise <a class="link" href="glib-Standard-Macros.html#NULL:CAPS" title="NULL"><code class="literal">NULL</code></a> is
returned. You should generally call <a class="link" href="glib-Unicode-Manipulation.html#g-utf8-normalize" title="g_utf8_normalize ()"><code class="function">g_utf8_normalize()</code></a>
before comparing two Unicode strings.
</p>
<p>
The normalization mode <a class="link" href="glib-Unicode-Manipulation.html#G-NORMALIZE-DEFAULT:CAPS"><code class="literal">G_NORMALIZE_DEFAULT</code></a> only

representation. <a class="link" href="glib-Unicode-Manipulation.html#G-NORMALIZE-ALL:CAPS"><code class="literal">G_NORMALIZE_ALL</code></a> also standardizes
the "compatibility" characters in Unicode, such
as SUPERSCRIPT THREE to the standard forms
(in this case DIGIT THREE). Formatting information
may be lost but for most text operations such
characters should be considered the same.

useful if you intend to convert the string to
a legacy encoding or pass it to a system with
less capable Unicode handling.

In order to sort filenames correctly, this function treats the dot '.'
as a special case. Most dictionary orderings seem to consider it
insignificant, thus producing the ordering "event.c" "eventgenerator.c"
"event.h" instead of "event.c" "event.h" "eventgenerator.c". Also, we

Convert a string from UTF-16 to UTF-8. The result will be
terminated with a 0 byte.
</p>
<p>
Note that the input is expected to be already in native endianness,
an initial byte-order-mark character is not handled specially.
<a class="link" href="glib-Character-Set-Conversion.html#g-convert" title="g_convert ()"><code class="function">g_convert()</code></a> can be used to convert a byte buffer of UTF-16 data of
ambiguous endianess.
</p>
<p>
Further note that this function does not validate the result
string; it may e.g. include embedded NUL characters. The only
validation done by this function is to ensure that the input can
be correctly interpreted as UTF-16, i.e. it doesn't contain
things unpaired surrogates.
