Inspect every bidirectional character in your text in detail, with its name, code point, category, and what it does.
Quick Answer
The Urdu Bidi Character Inspector lists each bidirectional character in your text and explains it. For every mark, embedding, override, or isolate it shows the name, the code point, the category, and the effect it has on direction, so you understand exactly what each one does. Everything runs in your browser.

What the Urdu Bidi Character Inspector Does
The Urdu Bidi Character Inspector takes each bidirectional character in your text and explains it in a table. For every one it shows the name, the code point, the category, such as mark, embedding, override, or isolate, and the effect it has on the direction of the text.
Where a detector tells you a bidi character is present, this inspector tells you exactly what it is and what it does.
Everything runs on your own device. Your text is never uploaded or stored, so it stays private while you inspect it.
How to Inspect Bidi Characters
- Paste your text. Enter or paste the text you want to inspect.
- Read the table. Each bidi character appears with its name, code point, category, and effect.
- Choose the columns. Show the effect and the index as you wish.
- Copy or download. Copy the list, or save it as a text file.
The Categories
The inspector groups each character into a category. A directional mark acts like an invisible letter of one direction. An embedding or an override opens a new direction context. An isolate opens a context that is kept separate. A pop character closes the last one that was opened.
What Each One Does
The effect column explains the character in plain words, for example that a right-to-left override forces the following text to run right to left, or that a first-strong isolate takes its direction from the first strong character inside it. This makes the behaviour clear without reading the standard.
Opening and Closing
Embeddings, overrides, and isolates come in pairs. An opening character starts a context and a pop character ends it. If the numbers do not match, the direction can leak into the rest of the text, which the inspection helps you spot.

Who Uses This Inspector
Developers use it to understand bidi markup in strings. Localization engineers use it to check direction handling. Anyone learning the Bidirectional Algorithm uses it to see the characters at work.
Accuracy and Limits
The inspector identifies each bidirectional format character by its code point and gives its standard category and effect. It reports the characters that are present; it does not run the full Bidirectional Algorithm to compute the final visual order.
Good to know: to see the resulting order, use the bidirectional text tester with its live preview.
Your Data Stays Private
The inspector runs fully in your browser with standard web technology. Your text is not uploaded or stored, and it is not sent to any analytics service. Only your star rating is sent, to record the tool’s rating. When you close the page, your text is gone.
Frequently Asked Questions
What does the Urdu Bidi Character Inspector do?
It lists each bidirectional character in your text with its name, code point, category, and the effect it has on direction.
What are the categories?
Directional mark, embedding, override, isolate, and the pop characters that close a context.
How is it different from the detector?
The detector tells you a bidi character is present, while the inspector explains exactly what each one is and does.
What are opening and closing characters?
Embeddings, overrides, and isolates open a direction context, and a pop character closes it. Unmatched pairs can cause problems.
Does it show the final visual order?
No. It explains the characters. To see the resulting order, use the bidirectional text tester with its preview.
Is my data safe?
Yes. Everything runs in your browser. Your text is never uploaded, saved, or shared.
Is this tool free?
Yes, it is completely free and needs no account to use.
Does it work on mobile?
Yes. It works on phones, tablets, and computers.
