Ésta función codifica la cadena de los <parameter>data</parameter> a
|
|
<literal>UTF-8</literal>, y devuelve una versión codificada.
|
|
<literal>UTF-8</literal> es una mecanismo estándarusado por
|
|
<acronym>Unicode</acronym> para la codificación de los valores de <glossterm>wide
|
|
character</glossterm> dentro de una corriete del byte.
|
|
<literal>UTF-8</literal> es transparente para planear caracteres <abbrev>ASCII</abbrev>,
|
|
es auto-sincronizada (significa que es posible para un programa
|
|
averiguar donde empiezan los caracteres de la corriente de byte) y puede ser usada con
|
|
las función de comparación normal para ordenar y otros. PHP codifica los caracteres
|
|
<literal>UTF-8</literal> sobre los cuatro bytes, así:
|
|
<table>
|
|
<title>UTF-8 encoding</title>
|
|
