lithium\g11n\multibyte\adapter\Intl
Extends
lithium\core\Object
The Intl
class is an adapter which uses certain string functions from
ext/intl
. You will need to have the extension installed to use this adapter.
Internally works with a fixed encoding of UTF-8. This means you can't use
this adapter for anything different than UTF-8 encoded strings. Silently
returns null
or false
when input string contains badly formed UTF-8
sequences.
