Symptoms

When function names, variable names, and Component Object Model (COM) object names use extended characters, you may receive the following error message from the script parser:
Invalid Character
An example of an extended character is the French "acute e." This problem occurs in Microsoft Visual Basic, Scripting Edition (VBScript) and in Microsoft JScript.

Workaround

To work around this problem, use square brackets around the function name in VBScript. The following is an example:

objectvariable.[functionname]

Status

This behavior is by design.

More information

The workaround complies with the European Computer Manufacturers Association (ECMA) script specification 262. Script specification 262 defines a specific set of characters that you can use.
