[BUG] jamovi files (.omv) not rendering

[ertugruluyar-github]

I am getting this warning or error:
"Unable to render the requested file, please try again later."

I have found a similar issue in here that "CSV files not rendering". This is beacuse of "%" character but the issue resolved.
In my jamovi file there are:
? (only in the text)
: (in the heading or the text)
( and ) (in the heading or the text)

• (in the heading or the text)
  . (in the heading or the text)

And some of my heading is long but the longest one is: "Linear Mixed Model-3.2.1: Hem Öğrenci Hem Okul Düzeyi Değişkenleriyle"
Other than these there is nothing abnormal.
