            Bug ID: 139588
           Summary: API: textRegion.CharLocale uses changed type
                    Variant/Empty to signal mixed languages. Should return
                    .Language = "und" or similar.

The announced example.

Testing by user code for the locale of a given text region is complicated by
the fact that the Object property (structure) textRegion.CharLocale is replaced
by a property of type Variant/Empty if no unambiguous result is found (multiple
language e.g.). 

Bad idea. 

ISO 639 offers "und" or "mul" as values for .Language in the respective cases.

The attached example contains code for the demonstration of the issue, and for
the unnecessary complications it may cause when user code needs to evaluate the
locale related properties of text. The code also demonstrates a workaround.

If old code needs to be protected, a property .CharLocale2 might help.
