Call lists without names, only numbers

[Kolyan]

The program is used with a transliteration plugin
It works well, except that there are no names in the call lists

In log it looks like this:
"02-16 12:29:09.830 I/VcardManager(31931): BEGIN:VCARD
02-16 12:29:09.830 I/VcardManager(31931): VERSION:2.1
02-16 12:29:09.830 I/VcardManager(31931): FN:

02-16 12:29:09.830 I/VcardManager(31931): TEL;X-0:+7xxxxxxxx

The call lists are created by Android. My app does not try to resolve the phone numbers to names. Does the Android phone app show names in the call lists?

Yes, the Android phone app show names in the call lists.
If not using Bluetooth Phonebook App, then names are shown on the car device in call lists.

And in bluetooth hci log on phone are text like this:

BEGIN:VCARD
VERSION:2.1
FN;CHARSET=UTF-8:Лоншаков Роман
N;CHARSET=UTF-8:Лоншаков Роман
TEL;X-0:+79211493666
X-IRMC-CALL-DATETIME;RECEIVED:20180219T182715
END:VCARD

You may try a different character encoding in the app's extended options.
