silent corruption and unrecoverably data loss with non-ascii (e.g. Unicode) characters

[clach04]

On any platform where default encoding is not utf-8 (e..g linux with C locale, or Microsoft Windows) corruption that can not be recovered from occurs.

Sample file content:

7bit ascii filename unicode content

This file will fail to save, no meaningful information logged to stdout.
Default logfile only indicates note id, not title/filename, example:

    2022-05-21 21:55:23,683 [ERROR] Error writing note: f3902b0e-07ef-4e6f-9896-2a23c1e9ca52

suqsequent sync will then upload empty file and server will loose history.
Will not show up in trash and history (restore) option is missing :-(

3 issues probably need to be corrected to address:

• error handling needs to be more robust and vocal
• refactor code to remove duplicate file writing code
• explicitly define (file) encoding
