Too long file name

[supukarmin]

The single notes export crashes if the name of a note is too long. I suggest to shorten the name and write a warning / note to stdout. It would also be good if errors regarding to the file system could be fetched by default and handled with a warning / error.

Sorry, I cannot reproduce this issue. Could you share the note for testing? Also what evernote-backup version are you using and what is your OS?

[supukarmin]

I deleted my Evernote account after exporting the notes. I can't also find the error itself anymore. It's gone. According to the bash history, I used these commands:

sudo apt install pipx python3.8-venv
pipx install evernote-backup --force
pipx ensurepath
pipx init-db
pipx sync
pipx export /evernote_export --single-notes

The machine was:

OS: Kubuntu 20.04.4 LTS
Kernel: Linux 5.13.0-39-generic
Architecture: x86-64
Python: 3.8.10
evernote-backup: 1.7.1
file system: ext4

Max title length in Evernote:
https://dev.evernote.com/doc/reference/Limits.html#Const_EDAM_NOTE_TITLE_LEN_MAX

EDAM_NOTE_TITLE_LEN_MAX	i32	255
The maximum length of a Note.title, in Unicode characters

ext4 is 255 bytes. As far as I understood the Evernote docs, they're talking about characters. So as soon as you get a single character which takes more than 1 byte up, you should get an error. With normal latin chars, however, you should probably not get any problems, I guess.
