Fixes #1786: Locale critical code now uses the english local for transmission. Fixes Turkish Problem.

Applied English Locale where localization is not expected as in internal recipe handling and IMC handling, basically which interacts with public API where we either require to enforce the incoming text with regex ([a-z0-9]) or just expect proper usage of the API, but with just using upper cases in recipe files it would break in Turkish Locale like

ALIAS

another option would have been to use `equalsIgnoreCase` in some cases, but not all applicable
