Convert file to UTF-8

1
Hi all, I'm using the logic (Import CSV) from the the CSV module  (https://marketplace.mendix.com/link/component/108605) to import a file and process it. It failed when i use the original file (CSV as filetype from a SFTP server) when it tried to read the lines. When i save the original file manually as CSV UTF-8 it works, but that needs to happen automatically. Tried a lot with encode, string to file, string from file and all the other actions but not with the right result.   How can i solve this? Is there a possibility to convert automatically a csv (txt) to UTF-8?   Error with the original file:   com.mendix.modules.microflowengine.MicroflowException:

Hi Jeroen,

Use GetAsString java action from SFTP module.

 

I hope this can help you.

Kind regards,

Hi Jeroen, try adding a byte order mark to the CSV file by using the java action below:

 


		// BEGIN USER CODE
		try {
			
			/* create UTF-8 BOM byte array */
			byte[] utf8BOM = {(byte) 0xEF,(byte) 0xBB,(byte) 0xBF};

			/* get string from doc, add BOM */
			String CSV = new String(StringUtils.stringFromFile(getContext(), csvDocument));
			CSV = new String(utf8BOM) + CSV;
			
			/* create byte result for inputstream */
			byte[] result = CSV.getBytes();
			
			/* store to mx filedoc */
			Core.storeFileDocumentContent(getContext(), csvDocument.getMendixObject(), new ByteArrayInputStream(result));
			return true;
					
		} catch (Exception e) {
			Core.getLogger(this.getClass().getSimpleName()).warn("Unable to add BOM " + csvDocument.getName(), e);
			return false;
		}
		// END USER CODE

make sure to import these libraries:

 

import communitycommons.StringUtils;

import java.io.ByteArrayInputStream;

 

GL!
