+## Description
+
+When using the Telerik Reporting in the same application that processes MS Office documents and PDF files with Spire.Office libraries, the text in the rendered reports gets truncated unexpectedly.
+
+This issue occurs even when the Spire.Office operations are performed on completely unrelated documents before rendering the Telerik report.
+
+## Cause
+
+The issue is caused by Spire.Office modifying the global state of `System.Drawing.StringFormat.GenericTypographic`. After Spire.Office processes documents, the `GenericTypographic` method no longer returns a `StringFormat` object with the expected format flags.
+
+**Expected StringFormat flags:**
+- `StringFormatFlagsLineLimit`
+- `StringFormatFlagsNoClip`
+- `StringFormatFlagsNoFitBlackBox`
+
+**Actual StringFormat flags after Spire.Office usage:**
+- `StringFormatFlagsLineLimit`
+- `StringFormatFlagsNoClip`
+- `StringFormatFlagsNoFitBlackBox`
+- `MeasureTrailingSpaces` (additional flag)
+
+The extra `MeasureTrailingSpaces` flag causes incorrect text measurement in Telerik Reporting's GDI wrapper, leading to text truncation in some scenarios.
+
+## Solution
+
+To resolve this issue, manually remove the `MeasureTrailingSpaces` flag from the `GenericTypographic` StringFormat after using Spire.Office operations and before rendering Telerik reports:
+
+````C#
+using Telerik.Reporting;
+using Telerik.Reporting.Processing;
+
+// Spire.Office operations
+Spire.Doc.Document document = new Spire.Doc.Document();
+var wordDocPath = "./wordtest.docx";
+var pdfFilePath = System.IO.Path.Combine("../../../", "wordtest.pdf");
+
+document.LoadFromFile(wordDocPath);
+Spire.Doc.ToPdfParameterList toPdf = new Spire.Doc.ToPdfParameterList();
+document.SaveToFile(pdfFilePath, toPdf);
+document.Close();
+
+// Fix the StringFormat issue caused by Spire.Office
+System.Drawing.StringFormat.GenericTypographic.FormatFlags &= ~System.Drawing.StringFormatFlags.MeasureTrailingSpaces;
+
+// Telerik Reporting operations
+// ...
+````
+
+## Additional Information
+
+This issue affects only older versions of Spire.Office that use the GDI+ engine for text rendering. Starting from version `9.2.0`, it does not rely on GDI+.
