In CaptureTextTemplates_language.rdl I have found a lot of defaults for capturing. But the names of the keys themselfes are not within that file. Instead of "Ctrl+C" with a German keyboard layout the text would be correct with "Strg+C". Any chance to also make the texts for the keys language dependent?
For existing recordings, you can always use the Find and Replace functionality.
I might assume that if you were using an authentic system configured for the language that it would rendeer the text appropriately. Assuming it's not doing that, I'll suggest you file a Wish Form/Bug Report to advise Adobe. (Link is in my sig)

I have reported that bug. Thanks.
