Render Unicode Supplementary characters in output PDF by Aspose.Cells for Node.js via C++

Normal Unicode characters are 2-bytes long while Unicode Supplementary characters are 4-bytes long. Aspose.Cells now supports rendering of these 4-bytes Unicode characters.

In the Unicode Character Standard, Supplementary Characters are the characters assigned code points from U+10000 to U+10FFFF. In other words, these are the Unicode characters greater than U+FFFF.

• In UTF-8 these characters are each 4 bytes long.
• In UTF-16 these characters require 2 surrogates (16-bit units).

Render Unicode Supplementary characters in output PDF by Aspose.Cells for Node.js via C++

The following screenshot shows how Aspose.Cells rendered the source excel file into the output PDF. As you can see all three Unicode Supplementary characters have been rendered exactly the same as done by Microsoft Excel.

Sample Code

You can use this sample code to convert source excel file into output PDF.

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");

// Load your source excel file containing Unicode Supplementary characters
const workbook = new AsposeCells.Workbook(path.join(dataDir, "unicode-supplementary-characters.xlsx"));

// Save the workbook
workbook.save(path.join(dataDir, "RenderUnicodeInOutput_out.pdf"));
