ModemManager 1.14.0: Can't send sms with some chars

[Stanke, Scott]

Hello ModemManager-devel,

Do you know if the following issue is resolved in ModemManager 1.16.0? I found the following link that looks like the same issue that we are experiencing on our Digi International cellular routers running MM 1.14.0:

https://todo.sr.ht/~mil/sxmo-tickets/92

A Digi International customer found that sending an SMS using our cellular router running ModemManager 1.14.0 with extended ASCII characters results in:

# 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'
I can reproduce the issue using the following test commands (if I send with “text” not including extended ASCII chars, the message is successfully sent):


# # mmcli -m 0 \

# > --messaging-create-sms="text='hello world范例',number='+16511234567'"

/bin/sh: can't create --messaging-create-sms=text='hello world范例',number='+16511234567': Read-only file system

# Successfully created new SMS: /org/freedesktop/ModemManager1/SMS/6

/bin/sh: Successfully: not found

# # mmcli -s 6 --send

# 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'

Thank you for looking at this. We are planning to release cellular router FW implementing MM 1.16 as backlog. I hope to provide our customer an update that MM 1.16 should fix the issue.

Best Regards,

Scott
