Dmitry Volodin commented on CAMEL-11527:
----------------------------------------

[~jpoth] camel-olingo2 component and OData 2.0 format are still actively using
Please also note, that camel-olingo4 component has the same problem and need to 
be fixed.
Can you fix camel-olingo4 in the same PR?

> camel-olingo2 uses upper-case UTF-7 as Accept header instead of lower case 
> utf-7
