Alive with activity: Tiles, notifications, and background tasks

Consider this an early question from a distant audience:
How can I use an ampersand character in the original English text and not in a foreign language using the Multilingual App Toolkit? There appears to be encoding issues with the toolkit that I'm not sure how to work around.
@Jared: The workaround is to translate using the editor, but leave the & in the target string. Once done, save and exit the editor. In the VS IDE, open the .XLF file with the XML editor and manually replace the %%amp; with your desired character.
Thanks for the advice Cameron, but once you apply the workaround you can't use MAT again until you put %%amp; back in the translations. I have half a dozen of these amongst 300+ entries across five languages. That's quite a mess to manage. Since my build time went from seconds to minutes with the inclusion of MAT, I'm beginning to question its usefulness.
A new version of the Multilingual App Toolkit has been released that resolves the issue with the matching %%amp; requirement in the target value. The version is v1.1.1075.0 as displayed in the VS IDE Extensions and Updates dialog.
Thanks Cameron. I had to uninstall and then reinstall but it has solved both my issues. My build times are back to mere seconds again.
