Dynamically selecting code pages for the input to an Event

You can use lookup/script aliases or retrieved scripts to dynamically select the appropriate code page for the input to an Event.

Prerequisites

•	The input data must be represented by single-byte characters.

•	No code page filter is added to the input connector that receives the input data.

To select code pages using a retrieved script

Add a retrieved script that includes the ConvCurrMsgToUC scripting function to the Event. See the Scripting reference for information.

To select code pages using lookup/script aliases

1	In the Runtime configuration view, right-click the Event and select Settings. The Runtime Event Settings dialog box opens.

2	On the Code Page tab, select Lookup or Variable and specify the alias settings. See the Design Center documentation for information about alias selection methods.

Lookup table syntax

<key value>    <code page>

Comments:

•	Use TAB to separate <key value> and <code page>.

•	Use quotation marks if <key value> contains white spaces.

•	<code page> must be a name listed in Code pages supported by the StreamServer.

Example 4

Lookup table

"Western Europe"   ISO 8859-1

"Eastern Europe"   ISO 8859-2

Turkish            ISO 8859-9

 

Example 5

Code page selection using a lookup table.

In this example the PageIN Event receives both ISO 8859-15 and ISO 8859-2 encoded input. The following lookup table is used to dynamically select the appropriate code page:

Western    ISO 8859-15
Eastern    ISO 8859-2
