ModemManager 1.14.0: Can't send sms with some chars

[Stanke, Scott]

Hi Aleksander,

I created a ticket with our IT team and our email communications appear to be working now.

I understand the command from the Digi router shell: "modem sms-text 16511234567 world范例" runs the following commands:

# # mmcli -m 0 \
 # > --messaging-create-sms="text='hello world范例',number='+16511234567'"
# # mmcli -s 6 --send

My test results, when running the above commands from the shell, shows the "/bin/sh: can't create --messaging-create-sms=text='hello world范例',number='+16511234567': Read-only file system" probably because I do not have the correct permissions when running from the shell. I will ask our Engineering team how to find if this filesystem error is seen when executing "--messaging-create-sms..." after the router shell command: "modem sms-text...".

Please will you confirm the  "mmcli -s 6 --send" command should not result in the following error when "text" includes Chinese characters? 

# error: couldn't send the SMS: 'GDBus.Error:org.freedesktop.ModemManager1.Error
.Core.InvalidArgs: Cannot prepare SMS to be sent: Cannot generate PDUs: Error pr
ocessing input text'

Your original response indicates that we should not see the "...Cannot generate PDUs..." error, but I want to be sure as my Team is requesting Engineering to provide OS builds addressing: "proper UTF-8 locale
either in the environment or in the filesystem".

Thank you.

-Scott

For some reason that I fail to understand, all emails I've sent to any
@https://linkprotect.cudasvc.com/url?a=https%3a%2f%2fdigi.com&c=E,1,P8KBlngGmEfdGrm7sA_F93VQoidV4GPswrcmticCWy2m6XfbnKhOujDQvcX06i1NyvXgI3Az_Gud8I6fo6lwQzFnFjrpKPWLKdjKLSEodhmTRINzPgr0RvFq-p8C&typo=1 address over the past year have bounced back. I've even tried with multiple email addresses, all get rejected. I hope you can look at the mailing list archives to read this response, and if you prefer, please use a different https://linkprotect.cudasvc.com/url?a=https%3a%2f%2fnon-digi.com&c=E,1,CkT0XNMEDtNXfff4o5GDqLRI0YhQles9ZEvrdi7MFkqzSBcgSPkii21afWkU1bRhUfCpoTTG-Ulc5R1yMVAgL28p_oESxSb9J8731nH6lmNPwsnkNY302p97&typo=1 email address :)

I have no idea what those "modem sms-text" and "modem sms-binary"
things are :) They are not part of the ModemManager project, so I assume those are some internal tools from Digi.
