|
Ésta función codifica el string <parameter>data</parameter> a
|
|
<literal>UTF-8</literal>, y devuelve una versión codificada.
|
|
<literal>UTF-8</literal> es una mecanismo estándar usado por
|
|
<acronym>Unicode</acronym> para la codificación de los valores de
|
|
<glossterm>caracteres anchos</glossterm> en un flujo de bytes.
|
|
<literal>UTF-8</literal> es transparente para caracteres <abbrev>ASCII</abbrev>
|
|
puros, está autosincronizada (lo que significa que un programa puede
|
|
averiguar dónde empiezan los caracteres del flujo de bytes) y puede usarse con
|
|
funciones de comparación de string normal para ordenar, etc. PHP codifica
|
|
los caracteres <literal>UTF-8</literal> en hasta cuatro bytes, así:
