Common questions about offline letter index conversions.
The converter supports English A-Z (mapped to 26 indices) and standard Arabic Abjad/Hijai (mapped to 28 indices) characters.
1-indexed is standard where A=1, B=2. 0-indexed sets A=0, B=1, which matches standard computer programming indexing patterns.
Punctuation marks (like commas, quotes, brackets) are left unchanged in the stream. Spaces are replaced by visual slash '/' dividers to maintain word separations.
