Creating reports and dashboards | Stimulsoft community forum

As title says, I encountered several problems when generating report in the ASP NET web application and all these problems arise in the Stimulsoft.Report.StiReport.ExportDocument method. The problems are as follows:

Pdf
System.Exception: "Exception in PdfFonts.GetFontMetrics, font 'Tahoma' step #40: 'The value U+D83D is not a valid Unicode code point value. Must not be in [ U+D800..U+DFFF ], inclusive. (Parameter 'value')'".
This problem does not always occur, sometimes generating report in pdf still works. At first, as it seemed to me, the problem was caused by the symbol , however, when deleting records with this symbol, the problem still arises.

Dbf
System.ArgumentException: "The output byte buffer is too small to contain the encoded data, encoding 'Unicode (UTF-8)' fallback 'System.Text.EncoderReplacementFallback'. Arg_ParamName_Name".
I can't say much about this problem, since it occurs every time a report is generated in this format.

ImageTiff
System.ArgumentOutOfRangeException: "Parameter "width" (System.Single) must be greater than 0, was 0 Arg_ParamName_Name".
As in Dbf problem occurs every time.

The problems occur only in these formats that we use, in others everything works correctly. I'll attach an example of report generated in xlsx format that when generating in the formats described above throw errors.

Hello,

Please send us a sample project that reproduces the issue for analysis.

Thank you.

Unfortunately, these errors occur in a highly integrated project, so I can't provide you with a sample project, all I can provide at the moment is an example of a report that throw errors when generating in the specified formats

Hello,

Ok. Please send us an mrt file with test data.

Thank you.

The project doesn't have mrt file, so I made a sample project that reproduces the errors described above.

Hello,

We need some additional time to investigate the issue, we will let you know about the result.

Thank you.

Hello, were you able to make any progress on solving the issues?

Hello,

We are still working on the issue, we will let you know about the result.

Thank you.

Hello,

We have made an improvement.
Please, check our next build when it will be available.

Thank you.

Great, the described issues was solved, however the report in tiff format still generated empty, this can also be seen in the sample project, can you look into this issue?
