I tried your code. It seems to display about every other line correct, and the rest garbled (But I can't really read cyrillic/russion). If I remove a comma or a space after a comma some places in the text, it affects the result (sometimes displaying more text correct or wrong), so it does seems to be a bug in there somewhere.
Apologies for any typos and strange grammar.

No. ReadString is not intended for reading plain text files. It is for reading null-terminated strings... i.e. if you create a file using "writestring", you can then read those strings using readstring. To read plain text, try using readline instead. It is in the documentation.

Hey,

I've tried a few things with this.
I change the encoding of the text file to UTF-8 with a BOM, UTF-8 without a BOM, UTF-16 with and without a BOM, Big Endien, Little Endien & Unicode ASCII Escaped.
I tried changing the line endings to DOS, UNIX and MAC terminators.
And I tried all of those things simply reading the file and displaying it, then reading it, writing it, reading the newly written file and displaying it again.

Each time I got a slightly different result but it was never perfect!

There's nothing further I can try so I think I may have to concur with you, this is a bug.

Thanks, fixed for the next version. It was caused by the way AppGameKit reads files, it currently reads them in blocks of 256 bytes, and if a UTF-8 character happened to get split across one of those boundaries it would no longer look like valid UTF-8. In this case AppGameKit assumes the 256 bytes it read are extended ASCII and tries to convert them (incorrectly) into UTF-8 causing all sorts of problems. The new version will read the entire string before checking if it is UTF-8 encoded.
