Hi Vlad!
I commented that I am having problems with the characters in Spanish when exporting / importing files in TXT format.
Testing the import of TXT files (exported by Android application), I have found "strange" characters as you can see in the following image:


You can also see that you have imported 2 notes (one with the contents of the file and another with the title and content of the file) when it is a single file that contains the text that you can see in the previous image. This also happens when you create a note with accents and other characters in AMN, export it and import it again.
By trying to visualize the contents of the TXT file exported by AMN, the characters can be read correctly.
I tried the beta version and I have not been successful either.
The regional settings for non-Unicode programs are correctly configured.
How can i fix this?
