Directory export crashes in Windows with certain characters - UnicodeEncodeError: 'locale' codec can't encode character

[micahellison]

Bug Report

Environment

• Jrnl --diagnostic output:

jrnl: v2.5
Python: 3.7.5 (tags/v3.7.5:5c02a39a0b, Oct 15 2019, 00:11:34) [MSC v.1916 64 bit (AMD64)]
OS: Windows 10

• Install method: pipx

Current Behavior

I was trying to reproduce the bug in #580 but hit an error message on the step where I'm exporting to a directory: UnicodeEncodeError: 'locale' codec can't encode character '\u043f' in position 9: encoding error

It seems so far that only certain Cyrillic characters are leading to this bug. Other non-English characters such as é seem to be fine, as does emoji characters.

Expected Behavior

jrnl should export the jrnl's contents without errors.

Repro Steps

• Start with an empty default jrnl
• Run the following in the Windows Terminal or the traditional Command Prompt: (confirmed in both)

jrnl Первая
mkdir .\jrnltest
jrnl --export md -o .\jrnltest

Other Information

Here's the traceback, which is the only output I get:
