Strange character in the top left of viewer page for Word documents

Good afternoon,

Some strange character appears when a word document is opened in the viewer with the htmlOption=true. I tested with mvn spring-boot:run and Tomcat server and issue happened for both.

We’re investigating this issue. It looks like these symbols are UTF-8 BOM. As soon as we have any update we’ll let you know.

I find where the error is.

I just had to add the encode as bellow:

return FileUtils.readFileToString(new File(htmlFilePath), StandardCharsets.UTF_8);


Thank you for sharing the fix. We’ll add this change into our code.
