recodeBlob()

The function recodeBlob() recodes a character set, like recode(), but works with a blob.

Synopsis

blob recodeBlob(blob s, string sourceEncoding[, string
                targetEncoding]);

Parameters


Parameter	Description
s	A blob that contains the character set.
sourceEncoding	The source encoding.
targetEncoding	The target encoding. The default target encoding is the project encoding.

Return Value

The encoded blob.

Description

The function encodes a blob. For possible encodings, see recode().
