Error when previewing in new version of stimulsoft report

[horusshih]

Dear all
I use stimulsoft report 2017.1.4 to create some mrt reports.

After using a new version of 2017.1.7, it shows "Error!" when I preview the mrt reports which are built with an old version 2017.1.4.

The error goes:
Failed to execute 'btoa' on the 'Window': The string to be encoded contains characters outside of the Latin1 range.
Failed to execute 'btoa' on the 'Window': The string to be encoded contains characters outside of the Latin1 range.
Failed to execute 'btoa' on the 'Window': The string to be encoded contains characters outside of the Latin1 range.

How can I fix this problem?

Hello,

The btoa function is a standard browser JavaScript function, and is designed to work with Base64 data. But it may be absent in older browsers, such as IE7, IE8. Please let us know the version of your browser.

Also, please tell us - is the error reproduced only on a certain report? If so, please send us a report template for testing. Also, if necessary, send a test set of data.

Thank you.

Hi, Vladimir

My IE version is 11.

Most reports, which are created in 2017.1.4, show error when I preview them.
I will also send one of these reports to support@stimulsoft.com.

Thanks for your reply!
