GNU sort does not have a -A option.



  $ sort -A

  sort: invalid option -- 'A'

  Try `sort --help' for more information.



Are you sure you are using GNU sort?  I suspect you are using a different s=
ort.  Probably a vendor sort.  Ask it for the version.



  $ sort --version

  sort (GNU coreutils) 8.13

Set the LC_ALL=3DC variable for sort.  Or at least LC_COLLATE=3DC.  If you =
are using a /bin/sh or derivative then you can do this on the command line =
for sort by placing the variable setting before the command.



  LC_ALL=3DC sort



If you are using one of the csh derived shells then you can use the "env" p=
rogram as a helper.  Some people document env only since it will always wor=
k correctly regardless of shell or function or aliases.



  env LC_ALL=3DC sort



In my ~/.profile I set the following.  It sets the LANG to UTF-8 so that I =
get unicode characters but overrides the collation sequence to be C so that=
 I always get byte comparisons for a traditional Unix sort order.  This wor=
ks for en_US.UTF-8 and for most other western languages.  But I have no ide=
a how it would interact with chinese big5 for example.  It may be a good co=
mpromise for you as well.



  export LANG=3Den_US.UTF-8

  export LC_COLLATE=3DC



There is an FAQ with more information here:

It is likely that your AIX locale is already set to C (or POSIX, an alias f=
or C).
