[jira] [Commented] (IGNITE-3140) C++: UTF-16 surrogate symbols are not serialized properly

["Igor Sapego (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-3140?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15284659#comment-15284659 ] 

Igor Sapego commented on IGNITE-3140:
-------------------------------------

We do not deal with the UTF-16 in C++ code. We expect user to provide us strings in a valid UTF-8 format.
Added test with malformed UTF-8 string where we are expecting an exception.

> There is an issue with serialization of a surrogate symbol with {{BinaryMarshaller}}. On Java side String's serialization logic was improved to support all the cases. Refer to IGNITE-3098.
> C++ serialization logic has to be updated as well. Please refer to the algorithm located in ignite-3098 branch in the following places:
> - {{BinaryUtils.utf8BytesToStr}} - serialization
> - {{BinaryUtils.strToUtf8Bytes}} - deserialization
> - {{IgniteSystemProperties.IGNITE_BINARY_MARSHALLER_USE_STRING_SERIALIZATION_VER_2}} controls which version of serialization logic to use (old or new).
