Chris,

I, for one, am a bit confused...sorry to be longish:

1. you wrote

Under 10.2, do shell script still fails when the path contains high asciis,
e.g.

do shell script "cd '~/Desktop/photos e'te''" or
do shell script quoted form of "cd ~/Desktop/photos e'te'" or

Both return an error (sh: cd ~/Desktop/photos e'te' : no such file or
directory)

However, the following seems to work :

set thePath to POSIX path of "U:Users:ac:Desktop:photos e'te'"
do shell script "cd " & quoted form of thePath & ";pwd"
-- "/Users/ac/Desktop/photos e'te'

2. None of these work when talking with Terminal, unfortunately :

set thePath to POSIX path of "U:Users:ac:Desktop:photos e'te'"
tell application "Terminal"
activate
do script "cd " & quoted form of thePath in window frontmost
end tell

Or
tell ...
do script ("echo " & quoted form of thePath) in window frontmost


3. A solution :

I found that if the Emulation -Escape 8bit chars with Ctrl-V option in the
window settings is selected, the following hack works fine :

set thePath to POSIX path of "U:Users:ac:Desktop:photos e'te'"
tell application "Terminal"
activate
do script "set thePath=`echo " & quoted form of thePath & "`; cd
\"$thePath\"" in window frontmost
end tell


4. You wrote:

Now, this is just plain curiosity, but
what's the relation between that and what I'm seeing -- e\314\201 --
(except that perhaps 101 is 0065, hence the "e" ?)

Why is it that the very same folder seems to receive two different
names/encodings in Terminal ?
Let me explain:
When using the file completion props of tcsh to change dir, I get to

~/Desktop/photos e\314\201te\314\201

However, using the trick mentioned above,

~/Desktop/photos \303\251t\303\251


5. Footnote :

Finally, let me correct, as the famous Hercule Poirot :

"Frenchman? No Sir, Belgian!"

Thanks !
