The string editor in the translations by default types from the left to right, which messes up the Arabic sentences, which goes from the right to left, especially when English words are included, including Acronyms like "OpenTTD", or translations of multiple lines. The simplest solution so far is to type in a new line, however, the new line disappears when the translation is updated.
If the text direction can't be changed, it would be helpful if there was a way to start new lines.
