Bidirectional Text

Bidirectional Text

As the name suggests, this is text in a document that goes both left-to-right (LTR) and right-to-left (RTL). An example of this would be having English words going in a left-to-right direction in an otherwise Arabic text (that goes right-to-left).

In Memsource:

  • Arabic, Hebrew, and other right-to-left languages are fully supported.
  • LTR and RTL text is automatically recognized in the Editors.
  • Neutral text (numbers, spaces, dots, etc.) can be marked as RTL or LTR with special RLM or LRM characters in the Editor’s menu by clicking on Edit and selecting Insert Symbol.

Note: You must display hidden characters to see the mark in the Editor's target. Do this by going to Format and clicking on Display Hidden Characters.

Completed File

The completed file carries the text-direction information within. While some applications can recognize it automatically (for example Microsoft Word), some applications do not support automatic recognition and the text direction must be set manually.

You can test your completed files by importing them back to Memsource to a project with RTL source language (Arabic, Hebrew...). If you open the job in the Editor, you will see the correct direction of the text.
