Editing Comparison of text editors (section)

== Right-to-left and bidirectional text ==
Support for [[Right-To-Left]] (RTL) texts is necessary for editing some languages like [[Arabic]], [[Persian language|Persian]], [[Hebrew]], and [[Yiddish language|Yiddish]] and the mixture of left to right (LTR) and RTL known as bi-directional ([[Bidirectional text|BiDi]]) support.

Depending on the algorithm used in the programs it might only render the bidirectional text correctly but may not be able to edit them. (e.g. Notepad++ 5.1.3 shows bidirectional texts correctly but cannot edit it and user should change the text direction to RTL to be able to edit RTL texts correctly.)

| {{ya}}<br />{{efn|name=gnuEmacsBidi|''GNU Emacs''<br /><br /> (1) According to a comment in the source file where the bidi support is implemented (http://git.savannah.gnu.org/cgit/emacs.git/tree/src/bidi.c accessed August 15, 2017), GNU Emacs doesn't fully conform to the Unicode Bidirectional Algorithm (Unicode Annex #9, a.k.a. UAX #9) in the way it wraps the lines of a bidi paragraph: "we are violating paragraph 3.4 of UAX#9. which mandates that line breaking shall be done before reordering each screen line separately."<br /><br />(2) According to the online GNU Emacs manual ([https://www.gnu.org/software/emacs/manual/html_node/emacs/Bidirectional-Editing.html#Bidirectional-Editing section 22.19 Bidirectional Editing], accessed August 15, 2017), for the purpose of changing paragraph direction, "Paragraph boundaries are empty lines, i.e., lines consisting entirely of whitespace character". This contrasts with the otherwise ubiquitous convention of regarding the newline marker (LF on Unix derivatives, including macOS, and CR+LF on Windows) as the paragraph separator in plain text documents. However starting with version 26.0.50, the bidi paragraph separator can be customized.}}
