A runtime error related to incorrect path

[kachok]

Hi,
I am having a runtime error as follows:
"C:\Users\%username%\Documents\Output Folder contains an incorrect path".

I use a LUA file for reading and writing the folder path.
I replace \ for \\ when writing the path.
The system language is Portuguese.
All works fine on a machine with English/Russian system language.

I think there is some kind of Character Encoding problem. Am I right?
Or anything else?

Will I experience this problem when just using the Windows Registry for this purpose?

P.S. Windows 10 update 1903

Can you show the actual code for writing and reading the path, as well as a sample output (text file)?

I've already fixed it, thanks.
I decided to use the Windows Registry instead of that.
It works perfectly now

UPDATE

The same error with the Croatian as the system language.
I haven't tested it properly I guess :(
I save and read the path using the Windows Registry.
The default path is "C:\Users\%username%\Documents\Output Folder". I use this path for saving of created image files.
What could be the problem?
Please help!!!
