Arabic: error messages for confirmation in ar.yml

[pion139]

Hi folks,
I am new here, so please don't blame me if this is not the right place to submit my question/bug report.
In the ar.yml file, the format of error messages is set as:

errors:
  format: "%{message}"

this works fine for most of the messages, however, for confirmation it looks like:

 confirmation: محتوى %{attribute} لا يتوافق مع %{attribute}

which leads to error messages looking like
"password content doesn't match password"
this is obviously a wrong error message, cause the right one should read something like:
"password confirmation doesn't match password"

I checked the en.yml file, and there the code looks like:

errors:
  format: "%{attribute} %{message}"
...
    confirmation: doesn't match %{attribute}

which magically works fine!!! (somehow rails resolves that the %{attribute} in the format and the %{attribute} in the message are two different fields, in Arabic, %{attribute} appears twice in the message, which leads to the wrong error message.)

Is there a way to fix this issue in the ar.yml without rewriting all error messages with the format set to "%{attribute} %{message}"?
