Sounds like you know about this.
But my problem is actually slightly different. I'm running a
do shell script "'shell script that returns Unicode'"
And it's been changed to
do shell script "'shell script that returns Unicode' > /path/to/file"
and then I do
do shell script "perl -e 'open F, qq(/path/to/file); print <F>'"
and the perl line gives me the error I'm trying to avoid!
I can only guess that you have a single quote or something in the
string that you pass to the command line. This is the trouble with
using uncontrollable strings in the command line. It's best to write
the string to a file in Temporary Items Folder and get perl to read
the string from there. That way you avoid actually having rogue
characters cause trouble.
This script does the equivalent of what you appear to be doing. I'm
afraid I don't talk much shellingo, so it's all in perl. Notice how
I've had to use backticks to avoid using ' in the comment lines, and
that I cannot use the hash either.
The script creates a file, writes unicode to it and displays the
result in the all-singing, all dancing most worthy successor to the
stupendous SimpleText -- I give you TextEdit!
set dox to "" & (path to +constant afdrdocs;)
-- (french quotes round the constant for 7-bit victims)
set pathname to dox & "aaa.txt"
set f to POSIX path of pathname
do shell script "cd / ; perl -e '
$f = qq (" & f & ") ;
q| create the file `aaa.text` |;
open F, qq(>$f) ;
q| Write the Unicode signature + three fancy a`s |;
print F chr(254). chr(255).
qq(\\000\\xe2\\000\\xe3\\000\\xe4);
close F;
q| Read the file and open it in TextEdit |;
open F, q (" & f & ") or die $! ; print <F> ;'"
tell application "Finder" to open alias pathname
