Text Direction Tester
Compare the same stored text under automatic, left-to-right, and right-to-left display rules. The previews use explicit Unicode direction and isolation settings so mixed Arabic, Hebrew, Persian, Urdu, Latin text, numbers, and punctuation can be tested accurately.
What the Tester Changes
The tool changes only the presentation direction. It does not reverse the string or alter the stored character order. Automatic mode follows the Unicode bidirectional algorithm, while the forced previews apply explicit left-to-right or right-to-left direction with isolated content.
