 Cyrillic SVG support is broken.
 UTF and ASCII svg file names works just fine.

 Example: try to upload this file to any media library on any WordPress
 installation:
 https://atlantsecurity.com/wp-content/uploads/2020/12/подготовка-аудит-ит-
 безопасности.svg

 It uploads fine, but does not display in Media. Also, when you try to
 insert it into a page or post, it inserts only word 2 and 3 from the file
 name.
 If you rename the same file to file.svg (ascii english) - it displays just
 fine, gets inserted just fine.

 Example
 word1-word2-word3.svg

 You try to insert it, it inserts word2-word3.svg only and the result is a
 broken image link.

 The file however is in the library, you can access it as the example I
 gave above.
