The Cyrillic string is not truncated by the number of characters when using the Connect Engine table

Good afternoon, I previously used version 10.5.8 together with Connect Engine to display third-party information from other databases, there were no problems
That is, I created a table pointing to a table from the MSSQL database and the information was displayed successfully

After that, I installed MariaDB 10.6.7 separately and I did the same thing and noticed one feature that now lines containing Cyrillic do not fit into the allotted number of characters.

In other words, I have a string in MSSQL: ИВАНОВА

When I created in MariaDB table with row VARCHAR(1) and get next:
10.5.8 = И
10.6.7 = ?

Change to VARCHAR(2)
10.5.8 = ИВ
10.6.7 = И

Change to VARCHAR(3)
10.5.8 = ИВА
10.6.7 = ИВ

Change to VARCHAR(4)
10.5.8 = ИВАН
10.6.7 = ИВ?

Change to VARCHAR(5)
10.5.8 = ИВАНО
10.6.7 = ИВА

If row without cyrillic, only latin or numbers for example IVANOVA
All excellent:

10.5.8 = I
10.6.7 = I

Change to VARCHAR(2)
10.5.8 = IV
10.6.7 = IV

Change to VARCHAR(3)
10.5.8 = IVA
10.6.7 = IVA

It seems that he began to somehow divide the multibyte Cyrillic and other special characters
