It says:
"""
When processing or displaying data
[...]
* Ambiguous characters behave like wide or narrow characters depending
  on context (language tag, script identification, associated font,
  source of data, or explicit markup; all can provide the context). If
  the context cannot be established reliably they should be treated as
  narrow characters by default.
"""

But we have no context here, right? So shouldn't we treat them as
narrow?

Benoit
