This is a font incompatability. You are using a font that doesn't have all the correct characters (there is a more specific answer in regards to iso-XXXX which has to do with standard in fonts and characters that I dont fully understand). So you must have replaced a standard font in your theme file with one of your choice or set it to one that is incompatible with your region/language. Going by your screenshot, I am going to assume you are in Russia or somewhere in that region of Europe. So I would suggest you find out what fonts support your language and drop that in your fonts folder, replacing a font you dont normally use (remember to make a backup first and rename the new one to the font you are going to replace). I can try to help you a little more but I am limited in my knowledge about these things, still, I am decent at troubleshooting.

So a did a quick search and found a few fonts for you, check out these fonts. You can google cyrillic truetype fonts and you *SHOULD* find one that will provide you with the missing characters. Again, I am not extremely knowledgeable in this area, I am just decent at troubleshooting.

Thank you friend! My Russian friends have already helped me - I replaced the file Fonts.xml and everything was OK. But there is another problem - doesn't work in "show logo"movies. In the tv show and in the movies - no. that is, partially. it doesn't work on 90 percent of movies.

I am glad you got that sorted out, There could be a few issues for not seeing the logos. First I would recommend using Artwork Beef to scan and process all movies. It will scan each movie, gather it's artwork and place it where it is needed. Second, I would suggest using Media Companion for storing all artwork and movie information along side your movies (in each movie folder). If you already are doing this, you need to ensure only 1 movie studio is listed(i cant tell you exactly where that setting is, but it is important to adjust this setting along with the rating being stripped down to only what it is rated (I can help you with that but should be done through PM). You also can set the Media Companion to download the extra art (clear logo etc.).  from Fanart.tv for movies and tv. Last, just a suggestion, when you are in your movies or tv shows, press up 2x (or what ever direction you need to activate the top of the screen menu) to get into the mode for selecting view modes and select a couple of extra views, then press backspace or esc to get back to your menu. Get back into your library, press up 2x again, select a different view, press down 2x. Next press up 2x again and go to the view you want to use by default and preps down 2x. Now press up 1x and go into "view options/change view) and enable the options you want to set, then press right 1x to go into "collection/change view" and you will see settings for the logos at the bottom of your screen and other parts depending on your selected view. Lastly, cycle through your different views until you get back to your desired view (this makes sure that what you picked gets activated correctly). This is all trial and error finding the right setting for your liking but it is well worth it!
