[jira] [Commented] (CAMEL-8191) Charset is ignored for SFTP producer endpoints

["David J. M. Karlsen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CAMEL-8191?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14261355#comment-14261355 ] 

David J. M. Karlsen commented on CAMEL-8191:
--------------------------------------------

I don't think the endpoint actually supports the charset option - it's just inherited by the more generic file component but not handled in the SFTP component itself.
The conversion actually happens before the sftp component.
Have a look at https://gist.github.com/davidkarlsen/19cb1c8af7a8c5bd249e where there are two alternative ways of solving this:
1) Giving the Exchange.CHARSET_NAME option (which will influence the converter) or
2) converting to a byte array yourself and choosing the conversion charset

> For SFTP producer endpoints option "charset" is ignored and the output file is created using platform-default charset (usually UTF-8). 
> The simple Spring context illustrates the issue:
> {code}
> <beans xmlns="http://www.springframework.org/schema/beans"
>        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
>        xsi:schemaLocation="
>        http://www.springframework.org/schema/beans 
>        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
>        http://camel.apache.org/schema/spring 
>        http://camel.apache.org/schema/spring/camel-spring.xsd">
>   <camelContext xmlns="http://camel.apache.org/schema/spring">
>     <route>
>       <from uri="stream:in?promptMessage=Enter something:" />
>       <to uri="sftp://localhost:22/vso/sandbox?charset=ISO-8859-1&amp;username=fake_sftp_user&amp;password=qwerty"/>
>     </route>
>   </camelContext>
> </beans>
> {code}
> This context defines a route that transfers the string entered by user via SFTP. If the user enters "Müller", I can see 7-byte message in the output directory (because "ü" is represented using 2 bytes in UTF-8). While it should be 6-byte message if the file was encoded in ISO-8859-1.
> This problem affects only SFTP endpoints. File and FTP endpoints treat the "charset" option correctly.
