Use attached LigaturesHistorical.docx and continue at 8 or proceed to generate own document\n2. Open MS Word and create a new blank document \n3. Insert some text\n4. Select some text\n5. Right click selected text and select \"Font...\" from the menu\n6. In tab \"Advanced\" set \"Ligatures\" setting to a different value\n7. Save document\n8. Run attached program with the document\n9. Open resulting document in MS Word\n10. See error \"Word found unreadable content...\"\n\n**Observed behavior**\nOpening a document with a ligature setting using MarkupCompatibilityProcessSettings and saving the document produces an invalid document.\n\n**Expected behavior**\nOpening a document with a ligature setting using MarkupCompatibilityProcessSettings and saving the document should produce a valid document.\nIf the file format version supports the feature the ligature setting should be retained as is.\n\n**Desktop (please complete the following information):**\n - OS: Windows 10/11\n - Office version 16.0.19929.20136\n - .NET Target: .Net Core 8\n - DocumentFormat.OpenXml Version: 3.3.0 .. 3.5.1\n"},{"Id":"9387955217","Type":"PullRequestEvent","CreatedAt":"2026-05-12T23:35:27","Actor":"dependabot[bot]","Repository":"dotnet/Open-XML-SDK","Organization":"dotnet","RawContent":null,"RelatedAction":"labeled","RelatedUrl":null,"RelatedDescription":null,"RelatedBody":null},{"Id":"9387955238","Type":"PullRequestEvent","CreatedAt":"2026-05-12T23:35:26","Actor":"dependabot[bot]","Repository":"dotnet/Open-XML-SDK","Organization":"dotnet","RawContent":null,"RelatedAction":"labeled","RelatedUrl":null,"RelatedDescription":null,"RelatedBody":null},{"Id":"9387955232","Type":"PullRequestEvent","CreatedAt":"2026-05-12T23:35:26","Actor":"dependabot[bot]","Repository":"dotnet/Open-XML-SDK","Organization":"dotnet","RawContent":null,"RelatedAction":"labeled","RelatedUrl":null,"RelatedDescription":null,"RelatedBody":null},{"Id":"9387954482","Type":"PullRequestEvent","CreatedAt":"2026-05-12T23:35:26","Actor":"dependabot[bot]","Repository":"dotnet/Open-XML-SDK","Organization":"dotnet","RawContent":null,"RelatedAction":"opened","RelatedUrl":null,"RelatedDescription":"Opened pull request \"\" (#2083) at dotnet/Open-XML-SDK","RelatedBody":null},{"Id":"9371979455","Type":"PullRequestEvent","CreatedAt":"2026-05-12T16:06:25","Actor":"dependabot[bot]","Repository":"dotnet/Open-XML-SDK","Organization":"dotnet","RawContent":null,"RelatedAction":"merged","RelatedUrl":null,"RelatedDescription":null,"RelatedBody":null},{"Id":"9342407408","Type":"PullRequestEvent","CreatedAt":"2026-05-12T02:11:09","Actor":"dependabot[bot]","Repository":"dotnet/Open-XML-SDK","Organization":"dotnet","RawContent":null,"RelatedAction":"labeled","RelatedUrl":null,"RelatedDescription":null,"RelatedBody":null},{"Id":"9342407396","Type":"PullRequestEvent","CreatedAt":"2026-05-12T02:11:09","Actor":"dependabot[bot]","Repository":"dotnet/Open-XML-SDK","Organization":"dotnet","RawContent":null,"RelatedAction":"labeled","RelatedUrl":null,"RelatedDescription":null,"RelatedBody":null},{"Id":"9342408547","Type":"PullRequestEvent","CreatedAt":"2026-05-04T23:54:12","Actor":"dependabot[bot]","Repository":"dotnet/Open-XML-SDK","Organization":"dotnet","RawContent":null,"RelatedAction":"closed","RelatedUrl":null,"RelatedDescription":null,"RelatedBody":null}],"ResultType":"GitHubEvent"}},"RunOn":"2026-05-17T03:30:26.2745268Z","RunDurationInMilliseconds":744}
