K-9: exporting settings always fails: global or individual account

[AvoidMastodonBlue]

Expected behavior

export success

Actual behavior

failure message. additionally the xml file is not fully written: truncated

Steps to reproduce

1. load k9
2. burger
3. export
4. fi set path
5. save
6. error
7. optional: file explorer to open xml

or

1. long click imap account
2. export only that one
   .. same results

Environment

K-9 Mail version: 5.403

Android version: 444

Account type (IMAP, POP3, WebDAV/Exchange):

all IMAP, about a dozen accounts

Because i am missing a reply button i had planned to export accounys, clear data, uninstall, remive leftover files, reboot, reinsrall

but cannot export

Problematically I can't rememver the password for one account so I'm stuck

Please provide a debug log. See https://github.com/k9mail/k-9/wiki/LoggingErrors

As I will not have access to resources for that soon I did capture with CatLog what might be helpful, an illegal character warning

[catlog406]

Steps

switch back to k9
long click account, export, set filename, error
burgers
export [all]
set filename
error

stop log capture

I have enabled all two both of k9's debug options

[catlog406]

Are passwords salted and hashed, or more easily reversibly hashed? Or is there another way to backup account authentication information?

[catlog406]

Ahhh

The problem is my From Name contains some emoji the exporter does not like. Other accounts have emoji as well but are not a problem. This was the from line exporter choked on:

[myname] 🐱🍴

perhaps there are other emoji needing checked against this.

That account now exports successfully.

Global export now completes successfully.

Please create a new issue if this is still a problem with K-9 Mail 5.7xx.
