-There are two types of strings:
-a <literal>Unicode string</literal> (default) and
-a <literal>byte string</literal>.
-</para>
-
-<para>
-A <literal>Unicode string</literal> corresponds to an ECMAScript string
-which contains Unicode characters.
-</para>
-
-<para>
-<literal>Byte strings</literal> contain a sequence of bytes.
-They are used to serialize Unicode strings
-to external data and deserialize from external sources.
-For example, the <link id="string_toutf8">toUTF8()</link> method serializes
-a Unicode string to a byte string using UTF8 encoding:
-<example>
->> '£'.toUTF8().toString('hex')
-'c2a3'  /* C2 A3 is the UTF8 representation of 00A3 ('£') code point */
-</example>
-The <link id="string_tobytes">toBytes()</link> method serializes
-a Unicode string with code points up to 255 into a byte string,
-otherwise, <literal>null</literal> is returned:
-<example>
->> '£'.toBytes().toString('hex')
-'a3'  /* a3 is a byte equal to 00A3 ('£') code point  */
-</example>
-Only byte strings can be converted to different encodings.
-For example, a string cannot be encoded to <literal>hex</literal> directly:
-<example>
->> 'αβγδ'.toString('base64')
-TypeError: argument must be a byte string
-    at String.prototype.toString (native)
-    at main (native)
-</example>
-To convert a Unicode string to hex,
-first, it should be converted to a byte string and then to hex:
-<example>
->> 'αβγδ'.toUTF8().toString('base64')
-'zrHOss6zzrQ='

+There are two types of strings:
+a <literal>Unicode string</literal> (default) and
+a <literal>byte string</literal>.
+</para>
+
+<para>
+A <literal>Unicode string</literal> corresponds to an ECMAScript string
+which contains Unicode characters.
+</para>
+
+<para>
+<literal>Byte strings</literal> contain a sequence of bytes.
+They are used to serialize Unicode strings
+to external data and deserialize from external sources.
+For example, the <link id="string_toutf8">toUTF8()</link> method serializes
+a Unicode string to a byte string using UTF8 encoding:
+<example>
+>> '£'.toUTF8().toString('hex')
+'c2a3'  /* C2 A3 is the UTF8 representation of 00A3 ('£') code point */
+</example>
+The <link id="string_tobytes">toBytes()</link> method serializes
+a Unicode string with code points up to 255 into a byte string,
+otherwise, <literal>null</literal> is returned:
+<example>
+>> '£'.toBytes().toString('hex')
+'a3'  /* a3 is a byte equal to 00A3 ('£') code point  */
+</example>
+Only byte strings can be converted to different encodings.
+For example, a string cannot be encoded to <literal>hex</literal> directly:
+<example>
+>> 'αβγδ'.toString('base64')
+TypeError: argument must be a byte string
+    at String.prototype.toString (native)
+    at main (native)
+</example>
+To convert a Unicode string to hex,
+first, it should be converted to a byte string and then to hex:
+<example>
+>> 'αβγδ'.toUTF8().toString('base64')
+'zrHOss6zzrQ='
+</example>

+or from an encoded string (0.2.3).
+The encoding can be
