Error in right-to-left language support

The editor (including the Alpha editor) currently displays right-to-left (RTL) languages as left-to-right text. This causes inconvenient display errors for punctuation, and especially complicates the translation of RTL sentences that include snippets of LTR text (for example, the documentation of a function that is translated to Urdu but must show function names in Latin script will display improperly in the editor.)
