[jira] [Commented] (CAMEL-7224) camel-smpp - fails to correctly send messages that require UCS-2 encoding

["Daniel Pocock (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CAMEL-7224?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13982288#comment-13982288 ] 

Daniel Pocock commented on CAMEL-7224:
--------------------------------------

The patch submitted for the related issue CAMEL-7225 may help in working around this.

It would be really helpful if the documentation on the camel-smpp page explained the difference between alphabet and coding attributes as they are different attributes that relate to the same thing.  This would make it easier for somebody to contribute a patch.

> If I try to send a string without any config options or headers to indicate alphabet/data coding/encoding, it appears to be sent using an 8 bit character set even if a 16 bit UCS-2 encoding is required.
> If I try to set CamelSmppAlphabet=-1 (for unknown) as a header, an invalid message is sent to the SMPP peer and it is rejected with SMPP error code 00000401
> If I try to set alphabet=-1 in the endpoint config though and if I also set CamelSmppDataCoding=8 then it correctly sends a UCS-2 message.
> Looking at the code (particularly the method SmppSmCommand.determineCharset()), it seems that it can ONLY send UCS-2 if alphabet == UNKNOWN_ALPHABET.  Using the value UNKNOWN_ALPHABET (-1) as a header triggers the problem with the SMPP peer so I can only set that value in the endpoint config.  This determineCharset() method should also recognise alphabet == ALPHA_UCS2
