Windows 10 – Fixing Gibberish Text Display in Some Apps

There are several steps you have to take:

1. You must use a DirectShow filter for subtitles rendering that supports Unicode (like DirectVobSub). Your movie playing software must of course use that filter, it's impossible to say how exactly since you didn't say what movie player you use.

2. You must use a font that has all the characters you need (e.g. Arial, the default, works fine, don't change it to something fancy as Hebrew support in fonts is patchy at best)

3. Most important: your subtitles must be encoded in UTF-8.

   a. If your subtitles are external, just use software like iconv (Windows version) to convert your subtitles into UTF-8, just make sure you use correct source encoding (Windows-1255 for Hebrew and Windows-1251 for Russian) and the target must always be UTF-8.

   b. If your subtitles are internal to your video file, you'll need to extract them first. For MKV files, use mkvtoolnix to extract subtitles, transcode them same as in "a" above and pack them back into MKV. For other video file containers, use their appropriate tools to extract subtitles.

Try :

• Use Chrome in incognito mode which disables extensions. If that fixes the problem, one of your extensions is the troublemaker.
• Reset Chrome settings to default.
• Try using a new user profile. If that works, then your Chrome profile is corrupted, and you need to continue to the next point.
• Export all bookmarks, list your extensions, then go to the folder %LOCALAPPDATA%\Google\Chrome\User Data and rename the Default folder. This will make Chrome, when started, create a new default profile. Import the bookmarks and install the needed extensions and login where required.
  All your data will still exists in the renamed Default folder, but wholesale copying to the new folder might restore the problem. You may delete the renamed folder once the new default profile is fully functional.
