network.request returns empty response on iOS and MacOS

I use network.request to retrieve data from my server… It is a text file…

Recently I found that, if the text file contains some weird characters such as [text]’[/text] or [text]–[/text](these are different from single quote or hyphen; they are[text]’[/text] and [text]-[/text]), then on iOS and the Mac network.request returns an empty response… event.status is 200, event.isError is false, only the response is empty…

In android, everything is normal…

Is this a Corona bug or an iOS thing? [import]uid: 64174 topic_id: 35184 reply_id: 335184[/import]
