Render Trademark and Registered Symbols in Word DOCX and PDF Files using C# .NET

Hi Team,

We are experiencing discrepancy while rendering the document, which consists of Registered Symbol® and Trademark symbol ™.


We observed difference while converting rtf/word document into word/pdf document by using ASPOSE.WORD licensed library which consists of Registered Symbol® and Trademark symbol ™.

Trademark symbol is rendering in a perfect manner while we see issue with Registered.

To understand better we have prepared a sample application which consists of text with both Registered Symbol® and Trademark symbol ™.

Please refer the screen shoots for inputs and outputs and attaching the sample application.

Regarding WORDSNET-20231, we have completed the work on your issue and concluded to close this issue with “Not a Bug” status. Please see the following analysis details:

We have observed that there is in fact a proper character everywhere. As you mentioned Calibri font, there is a significant difference between Calibri and Arial (there is Arial in your document) for Registered Symbol. But it is fine and obvious for different fonts to look different.

There is also no difference between Aspose.Words generated String and Copy-Pasted to the MS Word UI.
