About this tool
When RTL text (Arabic, Hebrew) is mixed with LTR content like numbers or English words, browsers sometimes reorder things unexpectedly. Wrapping the LTR/RTL portion with an isolate mark (U+2066–U+2069) tells the browser "treat this chunk as its own direction" rather than letting it blend into the surrounding text's direction.
