A new version of ePub3-itizer has now been released. See the first post in this thread or my github site (kevinhendricks) to download the latest version of the plugin.
https://github.com/kevinhendricks/ePub3-itizer
Changes in v058 since the last release:
- do *not* convert base level xml entities to their numeric form for <, >, and &
- convert named entities to numeric entities in text even inside of pre tags
Hope this helps,
