National characters in Open Tometo router shell

mackowiakp · 08-01-2017, 01:03 PM

I added my Country locale (pl_PL) to shell in Open Tomato based router Asus. Originally only en_US and en_EN locale where available.
Now it is possible to use it for example in vim-full editor, installed from Entware-ng.
I send emails from router using msmtp command like this:

Code:

/bin/echo -e "Subject: Mail z routera ASUS\r\n\r\n<text with Polish characters>" |/opt/bin/msmtp --debug --from=default -t my_user@gmail.com,my_user@other.domain

Such emails are sending via gmail account, used as mail relay.

Below content of /opt/etc/msmtprc file:

Code:

defaults
tls on
tls_starttls on
tls_trust_file /opt/etc/certs/ca-bundle.crt
 
account default
host smtp.gmail.com
port 587
auth on
user my_account@gmail.com
password xxxxxxxx
from my_account@gmail.com
#logfile /opt/msmtp.log

The codepage for my language is Latin-8859-2.

The result is as follows.
- in iPad mail client, Polish characters are display properly both for Gmail account and for other.domain account
- in Linux Thunderbird Gmail account, Polish characters are display properly
- the same Thunderbird but other.domain account, strange symbols instead Polish characters
- mail read via Web page for other.domain, strange symbols instead Polish characters

All other sources emails are display properly on all platforms.

Probably I have to add something to config file or to msmtp command, to tell client s about codepage.
I call to other.domain admin but they dont know why Polish character are display not properly in they own system. Shame...
I dont know what to do. Any help?

The other_domian server may mark certain characters as "unsafe". The mail reader is then responsible to either comply with the safe/unsafe encoding,and to display "safe" characters instead. Or to ignore the encoding and display what was in the original message.

Yep. Probably You are right. But can I do something to make Polish characters encoding as "safe" in msmtp command call?

Your send command may not be what is responsible. It might be the remote server doing it. You can try uuencoding the message as binary and see if that works. But it won't get you any closer to finding out where the error is coming from.

And, I'm not sure I'm correct. I'm guessing as well as I can. But after over 30 years on PCs and 15 on Linux, sometimes I guess pretty well.

OK. So how I can uuencode mail in msmtp command? There is no uuencode command in Entware-ng repo for ARMv7 based platforms.
BTW. I first sat behind the Unix console in 1983. There was martial law in Poland (maybe you know something about it). And during our studies we used computers that were a Polish copy of PDP-11 from DEC. So I can say "Once upon the time...."
