We need to create a "dummy language" for testing.
We need it for clarify which texts are translatable and which are not.
How can I copy content of English target to another target (for example Tatar) where all texts in Tatar column would be corresponding copy text from English with prefix (specifically "▲" character).
Source text: "Fehler"
English translation: "Error"
Tatar translation: "▲Error"
