- Move utf8_encode and utf8_decode into the strings chapter, since they were moved out of the XML extension in 7.2 - Recommend mb_convert_encoding, iconv, and UConverter::transcode when mentioning encoding in passing - Document UConverter::transcode, based on examination of source and upstream ICU docs - Make the language used more consistent, e.g. "convert" rather than "encode"/"decode", "encoding" rather than "charset" Closes GH-1418.

<para>
|
|
All the functions that serialize variables use the first
|
|
element of an array to determine whether the array is to be
|
|
serialized into an array or structure. If the first element has
|
|
string key, then it is serialized into a structure, otherwise,
|
|
into an array.

Strings should be encoded in UTF-8; to handle other encodings, convert

the string first using <function>mb_convert_encoding</function>,
