UTF-8 encoding

If there is a UTF-8 encoding issue in the database, When the post is done in the ArchivesSpace Client, possibly use the same mechanism that is used in the Archon migration tool:

In the Archon post method, see this line (https://github.com/archivesspace/archon-migration/blob/cfc9abe534e5c19b47de364625bab8535556cf31/src/org/nyu/edu/dlts/utils/ASpaceClient.java#L160):

post.setRequestEntity(new StringRequestEntity(jsonText, "application/json", "UTF-8"));

The corresponding line of code in the AT post method is (

at-migration/src/org/archiviststoolkit/plugin/utils/aspace/ASpaceClient.java

Line 166 in 55c4e7f

    
           post.setRequestEntity(new StringRequestEntity(jsonText, "application/json", null));

):

post.setRequestEntity(new StringRequestEntity(jsonText, "application/json", null));
