Hi, While working on an Arabic-script translation for TryRuby (PR #222 – Persian),
I noticed that text input in the editor is unreliable for Unicode content.
TryRuby currently uses CodeMirror 4.8, which has known issues with Unicode/BiDi text handling. This can result in incorrect character order and cursor behavior (e.g. Persian text rendering in reverse).
This is not a CSS or direction issue, but a limitation of the old CodeMirror 4.x text insertion logic. This directly affects the usability of Arabic-script languages.
Suggestion: upgrade CodeMirror to a newer version (5.x or later).
Even a minor upgrade should significantly improve Unicode input handling.
