Common questions
How does stroke order give away a cross-script disguise?+
Fluent writers of scripts like Devanagari, Arabic, or CJK follow learned, largely automatic stroke sequences and directions. Someone imitating unfamiliar characters tends to draw them like pictures rather than following the native construction order, which shows up under close examination.
What is a positional letter form, and why does it matter in this context?+
In scripts such as Arabic, a letter's shape changes depending on whether it appears at the start, middle, or end of a word. A disguise attempt often applies the wrong form for the letter's position because the writer has memorised isolated shapes rather than the connected script system.
