Single character prevents saving in OJS

I am trying to save instructions to authors for one of our journals. Saving fails because of one single character; a c caron (č). Replacing it with a regular lower case c lets me save, but I do not think the author in question would like me to replace a letter in his name.

I have tried using both “č” and “č” in the source. Both cause OJS to “hang” when clicking “Save”.

What could cause this?

Could you share your php logs when it happens?

My guess is you need to change you DB charset: If your DB is not able to store the char, it will return an error.

There are some ways to fix this… but let’s confirm the error first.
