Stream read error opening UTF-8 file

Hi Ansgar,

Having the following reproducible issue.

SQL file saved in MS Visual Studio with format "Unicode (UTF-8 Without Signature)".

Empty file, or just a few characters, doesn't seem to matter.

If I then try to open in Heidi (selecting the "UTF-8" encoding), I get an error: Stream Read Error. Heidi fails to load the file but from then on Heidi holds a lock on it. I can't edit it in any other application either. After killing Heidi the file is unlocked.

I turned on debug logging but there is nothing in the log:

"/ 2021-04-30 13:11:59 [] / / Loading file "P:\xxx.sql" (2 B) into query tab #1 ... /

I am attaching the file.

If I try to load the file with autodetect then I get this:

The issue does not arise if the file is saved in format "UTF-8 with Signature" in Visual Studio (or Notepad++).

The issue is especially frustrating because if a dev saves a file in UTF-8 without signature and I try to open it, I have to restart Heidi to regain access to the file.

Thank you for your work on Heidi!

The attached file seems broken, it just contains the 2 characters "xF". Probably that's an issue in my upload logic, not sure. Could you upload it somewhere else?

Yes the attached file only contained those two characters.

Hmm, that is interesting. If I add more characters to a file then the issue doesn't arise.

However, often I create a file in Visual Studio (which adds it to source control), and then open it in Heidi to write the actual SQL. So I guess the point is Heidi shouldn't break on opening an empty file, or a file with some dummy characters.

Thanks!
