What the Urdu Mixed-Direction Text Tester Does
The Urdu Mixed-Direction Text Tester is for text that mixes right-to-left Urdu with left-to-right English and numbers. It splits the text into segments by direction, counts every switch from one direction to the other, and points out the boundaries where the layout could go wrong.
Where the bidirectional text tester gives the full picture, this tool focuses on the switches and the boundaries, the places mixed text most often breaks.
Everything runs on your own device. Your text is never uploaded or stored, so it stays private while you test it.
How to Test Mixed Text
- Paste your text. Enter a mix of Urdu, English, and numbers.
- Read the switches. See how many times the direction changes.
- Check the segments. See each stretch of one direction, in order.
- Copy or download. Copy the report, or save it as a text file.
Direction Segments
A segment is a run of characters that share a direction, right-to-left, left-to-right, a number, or a neutral stretch of spaces and punctuation. The tester lists the segments in order, so you can see the shape of the mix at a glance.
Direction Switches
A switch is a point where a strong right-to-left segment meets a strong left-to-right one, or the other way round. The count of switches tells you how tangled the text is. A single Urdu sentence with one English word has two switches, into English and back.
Boundary Problems
Trouble happens at a boundary when a neutral character, like a bracket or a full stop, or a number sits between two opposite directions. The neutral can attach to either side, and a number always runs left to right, so the tester flags these spots as the ones to check in the preview.

Who Uses This Tester
Developers and designers use it to check mixed labels and messages. Translators use it for bilingual text. Anyone mixing Urdu and English uses it to see the switches.
Accuracy and Limits
The tester classifies each character by its Unicode range and groups it into segments. It counts switches between strong directions and flags neutral and number boundaries. It is a practical guide to mixed text, not a full run of the Bidirectional Algorithm.
Good to know: the live preview shows the actual browser layout with dir=auto.
Your Data Stays Private
The tester 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.
