How to use
- Paste your Arabic text into the box.
- Tick the folds you want. The common ones are on by default, and the riskier ones, such as taa marbuta, are off.
- Read the counts of what changed in each category.
- Copy the result for your search index, keyword list or comparison.
What it checks and how it works
Arabic has spelling variants that readers treat as one letter but software treats as different characters: alef with hamza, madda or wasla (أ إ آ ٱ) against plain alef (ا), alef maqsura (ى) against yaa (ي), taa marbuta (ة) against haa (ه), tashkeel marks and the decorative tatweel (ـ). The tool applies the folds you choose, character by character, using the letters in the Unicode Arabic block, and can apply Unicode NFKC (UAX #15) to fold presentation forms back to base letters.
Folding is for matching, not for publishing: it can merge different words, and taa marbuta to haa changes the spelling of the text. Keep the original text for display.

Questions
About this tool
No. Normalization is for matching and comparison. It can merge different words into one, so publish the original spelling.
Turning ة into ه merges words that differ only by that letter and changes how the word is written. Turn it on when you match user queries that mix the two spellings.
It maps presentation forms, such as the joined shapes copied from some PDFs, back to the base letters, following Unicode Normalization Form KC in UAX #15.
