Hi Gaurav,

Thanks for your patience.

Please note that Aspose.Words requires TrueType fonts when rendering documents to fixed-page formats (JPEG, PNG, PDF or XPS). You need to install fonts that are used in your document on the machine where you're converting documents to PDF. Please refer to the following article:

How Aspose.Words Uses True Type Fonts

After investigating this issue, we have noticed that you are facing this issue due to missing fonts "Arial Unicode MS" and "DotumChe". Please install these fonts to get the correct output. Please let us know if you have any more queries.

Can you provide DotumChe font or a link may be for linux?

@susil,

Thanks for your inquiry. You can try Google Noto Fonts which is a collection of fonts that cover most of the ranges specified in the Unicode standard. Hope this helps you.

Related to this issue:

    val stream: InputStream = new ByteArrayInputStream(htmlDecoded.getBytes(StandardCharsets.UTF_8))
    val loadOptions = new LoadOptions()
    loadOptions.setEncoding(StandardCharsets.UTF_8)
    val doc: Document = new Document(stream, loadOptions)
