Protocol Action: 'Right-to-left scripts for IDNA' to Proposed Standard

[Abdulrahman I. ALGhadir]

Hey,

Well as we know the IDNA protocol didn't adapt bidi algorithm (UAX #9) fully. They disallowed all bidi markers (LRM,RLM,...) which are they used to solve problems from this kind.

So, what can be done?
1) adapt or create new algorithm in IDNA protocol to solve this issue (doubt it).
2) make all hyper links to be treated in special way rather using UAX#9 (application wise possible).
3) enhance the existent bidi algorithm by adding new rules to support hyperlinks (possible).

Thank you,

Displaying L1.R2.R3.L4 as L1.R3.R2.L4 in an LTR context is really
confusing because it breaks the logical aspect and the implied
hierarchy of domain names. Furthermore, it makes the domain names
unnecessarily inconsistent with original design of DNS with respect to
RFC1034. I understand that this is in compliance with UAX9 and is
related to the statement :

> All the text in this document assumes that text containing the labels

But why use UAX9 for "text containing the labels"? why not only for labels?
