Illegal characters in URL with ajp13

When using mod_jk (ajp13) to reverse proxy /nuxeo characters such as spaces, (, ), ... in the URL are considered illegal.

JkMount /nuxeo ajp13
JkMount /nuxeo/* ajp13

Reverse-Proxying through rewrite engine works fine though:

RewriteRule /nuxeo(.*) http://localhost:8080/nuxeo$1 [P,L]

To reproduce, go to workspaces and create a document with a space in the title
