Issue while rendering converted HTML from docx on another page

Hi Team,
After converting docx to html we are embeding generated html page on our application.
This generated html is causing issues with existing text on page it is making few of the characters bold and few of them as it is e.g. Test 123

To debug this issue we removed base64 from generated font-faces and it was working.
Can you please have a look into this issue?

Generated font-face which is causing issues.

@font-face {  font-family: 'Arial';  font-style: italic;  font-weight: normal;  src: local(''), url('data:application/x-font-woff;[huge base64 of font data]');}

After changing above font-face to below we didn’t saw the issue

@font-face {  font-family: 'Arial';  font-style: italic;  font-weight: normal;  src: local('');}

Issue is occurring when we are embedding generated html on other page which affects other fonts . Also this is very specific to this document only.
Let me know if you need any more information for my side.

Your issue is related to Aspose.Words. So, we have moved it to Aspose.Words’ forum where you will be guided appropriately.

@Vishaldekar Most likely the problem occurs because when you export your document to HtmlFixed format font subset is embedded into the output CSS. Font subset means that only glyphs used in the exported document are present in the font. Once you insert the exported HtmlFixed document on your page, your page uses the font subset from HtmlFixed and if text on the page uses the same font there might be a situation when there is a glyph that does not exist in the font subset and alternative font is used.

You can resolve this by setting UseTargetMachineFonts option. In this case, Aspose.Words does not embed fonts into the output HtmlFixed document and fonts installed on the target machine are used.
