Re: bash: remove the format string "%q" in the unicode3.sub

[address@hidden]

Hi chet

Thanks for you help.

1. This file:

    http://git.savannah.gnu.org/cgit/bash.git/tree/tests/unicode3.sub?h=devel&id=74b8cbb41398b4453d8ba04d0cdd1b25f9dcb9e3

When executed to the 3 line:

    "$payload"

On my target the output was:

    unicode3.sub: line 3: 5�@3�+�S8����: command not found

not the ANSI-C style quoted string like: $'...' in the changed compared file intl.right, the same for the 5 line.

    http://git.savannah.gnu.org/cgit/bash.git/diff/tests/intl.right?h=devel&id=74b8cbb41398b4453d8ba04d0cdd1b25f9dcb9e3


2. The fixed for

    printf %q "$payload"

in intl.right is fine for me.

Hi all

When I run the tests for the bash, the sub-test unicode3.sub of intl.tests
failed.

The sub-test unicode3.sub contain the following:

    payload=$'\065\247\100\063\231\053\306\123\070\237\242\352\263'
    "$payload"
    printf %q "$payload"

In this situation, the format string "%q" in command printf means that when the
character in the payload is not in {alpha & digit & punctuation & ISO
646(7-bit)}, it
would print the string with ANSI-C style quoted string: $'...' , we can
check the source code

This has already been changed in the devel branch (back in May, 2015), and
the test case and tets output was changed at the same time.
