I just dicovered a new issue in my code, when a file name contains one
open left curly bracket. Sure, a right bracket and other types of
brakets will case same issue.

For example, I have a file named "Test { .txt".

My code takes specific file names (only the tails, no directory) and
writes them to other files as strings.
Due to automatic char escaping happening in this process, the string representing the file name will look like this: "Test\ \{\ 2.txt"

Which is fine.

Now my code will read those strings from the files and look them up, if
they still exists on the drive.
This is done by:

set path [file join $dir $tail]
set flag [file exists $path]

where "tail" is the variable containing the file name and "dir" is the
variable containing the directory whre the file is looked up.

The result of the "file join" command is: "C:/test2/Test/ /{/ 2.mpasm"

So all the excape chars are replaced by slash and I get the wrong file
path.

How can I avoid this issue?

Many thanks

Thanks! You answers got me thinking.
The issue was caused by writing data as a list, not as a string.
Problem solved.
