transcodeToString() Operation

set aString = aBlob.transcodeToString(charset);

The operation transcodes blobs encoded with a given character set into an internal string. The returned string is always UTF-8 encoded.

aString

Can be any variable or object attribute having type String. 

aBlob

Can be any variable or object attribute having type Blob.

charset

Specifies the encoding of the characters stored in aBlob.
charset can be any variable or object attribute having type String and denoting a valid character set (e.g. UTF-8, ISO-8859-1, etc.). A list of supported character sets can be found in Charset Definitions.

This example transforms a blob that contains ISO-8859-1 encoded characters into an internal string:

set aString = aBlob.transcodeToString("ISO-8859-1");
