FIX: Some RTF attachments render incorrectly Print ZTN1735 ID: ZTN1735 This Zetafax technical note applies to: Zetafax Server v2009 and earlier. Symptom Attaching an RTF file to a new fax message in the Zetafax API (COM API, C API and Z-SUBMIT) results in the RTF file being rendered as control codes, rather than as readable text. Cause The problem is caused by a null character that can appear in some RTF documents – particularly those created using WordPad. Resolution A hotfix is available for this issue. Please contact Technical Support for further information. Last updated: 6th May 2009 (GR/MW) Keywords: Zetafax API, rendering, rtf
