SMS text showing "part/text/plain"

[jerry-ne]

Hi Tibor, I am not sure, why now I can see "part/text/plain:" before SMS text. See this picture:

I am using the latest version of your app v.5.4.0.

what message is it? How was it sent?

[jerry-ne]

Text message, medium length (2 SMS) but for one unicode char ('í') it was transformed to MMS in another SMS app. I guess it was not delivery because for no answer. Also I have blocked MMS in Tmobile. It will be nice to see status of delivery also.

[tibbi]

is there any way to reproduce it reliably?

[jerry-ne]

Yes, I can easy reproduce it.

Send this text to someone:

Ahoj XYZXY, aaa bbbbbb. ABCABC AA bbbbbb bbbbbb, ABC bbbbb bbbbbb? bbbbbba can oo bbbbbb 
bbbbb. bbbbbbA can oo bbbbb bbbbb vv bbbbbbCC. bbbbbb bbbbbb bbbbbbD bbbbb bbbbbb DDBB 
bbbbb bbbbbb AAAA bbbbbb, DDDDDD. bbbbbbDDD 123456789aB bbbbbb bbbbbb. CCC DDDD bbbbí. bbbb, bbbbb.

The length of text is 279 chars. There is one spec. char: í. I tried to send it to contact with +420 and without and there is no different. LG G8s ThinQ, Tmobile CZ, blocked MMS.

cannot reproduce it. Do you have Czech system language set?

[jerry-ne]

Yes. Czech system.

I have the same issue so nothing to do with a Czech system. Please fix this.
