Summary0006269: Handle unsupported characters
Description

I orignally posted this question here: https://opcfoundation.org/forum/opc-ua-standard/handle-unsupported-unicode-characters/

To summarize:
Let's say I have an application which displays a String data type on some kind of GUI (the String value is tied to a OPC UA variable node). My GUI only supports displaying latin-1 characters, for this reason I want to limit the range of unicode characters that can be set to only include characters that can be encoded as latin-1.

The specification states:
"This Built-in DataType defines a Unicode character string that should exclude control characters that are not whitespaces"

Is it allowed to exclude (or rather reject) other unicode characters as well?

Would Bad_WriteNotSupported or perhaps Bad_OutOfRange be a valid error code if unsupported characters are received?

TagsNo tags attached.

Clarify that Bad_OutOfRange is the appropriate code to use when a client write or method call presents a Server with a string with unacceptable chracters.

Added clarification for Bad_OutOfRange:
This result code can be returned for any value that has the right DataType but does not comply with the restrictions defined by the Server implementation e.g. if a written String contains unsupported characters.
