Translating full html in drupal

I've been working today on the new encantsbcn site.

For a while there was a problem when trying to translate blocks wich where in Html format. Once you tried to translate you'd get the following message: The string blocks:block:1:body for textgroup blocks is not allowed for translation because of its text format.

After fighting Drupal for a while, looking for work arounds and searching the web I found a simple answer in stackexchange

You just have to navigate to /admin/config/regional/i18n/strings and enable the formats you'd like to be translatable.

Once enabled you'll be able to translate the block in question even if in Html format, but be warned the actual block is duplicated, not simply translated.
