TextEncoding

A text encoding specification is a set of numeric codes used to identify text encodings. It specifies the base text encoding, the text encoding variant, and the text encoding format. It is used, for example, to identify the encoding of text passed to a text converter. Two such specifications are needed--for source and destination encoding--when calling the Text Encoding Converter or the Unicode Converter to convert text.

You can use these data types when you create a text encoding specification:

• TextEncodingBase, described in "Text Encoding Base" (page 31)
• TextEncodingVariant, described in "Text Encoding Variant" (page 35)
• TextEncodingFormat, described in "Text Encoding Format" (page 40)

A text encoding specification is defined by the TextEncoding data type.
