PRI #185 Revision of UBA for improved display of URL/IRIs

The Unicode Bidirectional Algorithm (UBA), specified in UAX #9, was designed
for handling ordinary text, and predated the rise of the web. Unfortunately,
IRI/URLs are not ordinary text; they are syntactically complex in ways that
don’t work well with the UBA. That causes IRIs that contain right-to-left
text (such as Arabic or Hebrew) to appear jumbled, to the point where the
IRIs are either uninterpretable, misleading, or ambiguous. In particular the
ambiguous displays could cause security problems.

The background document for this PRI provides a detailed description of the
problem, and proposes a solution. The Unicode Technical Committee would like
feedback on the feasibility of the proposal, and in particular, on the open
issues listed in the background document.
