Dear group

I got into a nasty trap using a string consisting of a single
accented character.

When I copy&paste this string, it changes (a useless pair of \( \) is
removed) !

This is quite annoying, since I am using this string in a symbolic
calculation.
I got two versions of my string which are visually absolutely
undistinguishable,
altough they are not identical.

Here an example:

1. InputForm[]
2. Enter v with tilde via palette, add ""
3. Evaluate
4. Delete the string, paste it back again
5. Evaluate again

\!\(InputForm[\*"\"\<\!\(\(v\&~\)\)\>\""]\)
"\!\(\(v\&~\)\)"

\!\(InputForm[\*"\"\<\!\(\(v\&~\)\)\>\""]\)
"\!\(v\&~\)"

In[424]:=
\!\(InputForm[\*"\"\<\!\(\(v\&~\)\)\>\""]\)
Out[424]//InputForm=
"\!\(\(v\&~\)\)"
In[420]:=
\!\(InputForm[\*"\"\<\!\(v\&~\)\>\""]\)
Out[420]//InputForm=
"\!\(v\&~\)"

Any suggestions?

Cheers
Ben
