 * I’ve been encountering problems with Advanced Text and Advanced Heading blocks
   when the text content contains certain non-English characters. Recently I’ve 
   noticed the problem with some Turkish letters. For example, create one of those
   blocks and then copy-paste the following word (the name of a Turkish town) into
   it:
 * Ovacık
 * Note that the letter before the ‘k’ is not an ‘i’.
 * The blocks will accept this word and it works fine in the front-end. However,
   do the following:
    – Save the post. – Exit the editor. – Re-open the post in 
   the editor again.
 * Result: The block in which you inserted the above word will fail, with a message:“
   This block contains unexpected or invalid content.”.
 * Note, using the ‘Recover’ option seems to work 100% of the time and the issue
   does not seem to affect the front-end. It just requires a ‘recover’ every time
   the page is opened for editing (and every block such characters are used in has
   to be individually recovered, which can be a nuisance in some cases).
 * I’ve encountered the issue with other characters, too, though I did not log them
   since I didn’t realize at the time that those characters were triggering the 
   issue.
 * Using the same word in default WordPress blocks (the paragraph block, for example)
   does not cause the error. It seems specific to GreenShift.

 * I tried. But can’t see any issue. [Check it](https://monosnap.com/file/A5A6NJyPaAHONuagfDmxsI4pJ5OTgP)
 * Maybe you have some extensions which modifies content before saving. As I remember,
   some browser auto translator extensions can do such bug

 * Hmmm. It is reproducible for me on two systems with different plugins / extensions
   though it is possible I have something the same on both.
 * FYI: One step your ‘Check it’ video omits is exiting and then re-opening the 
   editor. I do not get any issue simply by saving it. I only see the issue after
   exiting and then re-opening the editor. Did you do that step when you tested 
   it?

 * Yes, video also has this, but reload is so fast so it looks like it was not reloaded.
   I recommend you to test in browser without extensions and on other computer

 * The issue doesn’t seem to be happening any more. I’ll close this issue now. Thanks
   for following up.
