CharSet Property

Identifies the character set of the data file.

Syntax

[ sValue = ] TDC.CharSet

Possible Values

sValue String expression that describes the character set used for the data file. If no value is supplied, the input file is interpreted using codepage 1252 (Western Alphabet). See the table below for the full listing of possible values for this parameter.

The property is read/write. The property has no default value.

The following table defines the list of possible values for the character set codes.

In normal use, the CharSet property is set in the Web page (or is left at its default value) and never referenced again. Although you can set the property when the data has been loaded, this will not change the interpretation of the data. The only exception to this is if the DataURL property is set to a new value that forces all properties to be reevaluated.

The Tabular Data Control (TDC) determines the codepage for the source data file incorrectly in certain scenarios. The problem can occur if the ambient codepage is Unicode, in which case the TDC assumes that the bound data is also Unicode, which is not necessarily true. When the TDC attempts to identify the Unicode signature in the byte-reversed case, it compares the value incorrectly. If the TDC reads a variable that is uninitialized, it waits for an excessive period of time in an attempt to identify the ambient codepage. If the TDC changes its codepage because it sees a Unicode signature, it fails to update its CharSet property. Therefore, to avoid potential problems associated with incorrect codepage identification, the CharSet property can be set explicitly when declaring the TDC, as shown in the following example.
