"Emoticons" don't get exported to Word..

Good Morning;

We have migrated our preproduction version from confluence 3.5.9 to 4.3.7.
During the testing mode, one of our user has noticed that the emoticons are not exported into word.
This seems to be a bug reported here :
https://jira.atlassian.com/i#browse/CONF-25599

We need a really urgent workaround because we cannot install the version 5.2 where the bug seems to be fixed.

Thank for your answer.
Best regards

Stéphane J.
