Single quotes pass \ intact, but double quotes see \ as an escape to put a double quote into the string:
I use single quotes first and most for their almost complete immunity to unintended meta-behavior. I figure it saves cycles in the shell.
But, hey, the answer is in there somewhere. I flash on FRED buffer scripts where we were seeing 4 or even 8 \ as the number halved every time you went through a meta-wall like the buffer!

vte [-2] [-A] [-a] [-B image] [-b] [-C] [-c command] [-D] [-d] [-f font] [-g] [-h] [-i] [-k] [-n] [-r] [-S] [-s] [-T] [-t terminal-type]
DESCRIPTION
vte is simply a window wrapped around the vte embeddable terminal emulation control, which does most of the work for gnome-terminal. vte is
used mainly to test the control. Most users do not need to use vte directly, but use gnome-terminal instead.
OPTIONS
The following options are supported:
-2 Toggle double buffering. Enabled by default.
-A Toggle antialiasing. The default is that of the current GTK+ default.
-a Toggle audible bell on/off. If audible bell is enabled, visible bell is disabled. If audible bell is disabled, visible bell
is enabled. Audible bell enabled by default.
-B image Use image as background.
-b Toggle cursor blinking. Enabled by default.
-C Open a "console" connection.
-c command Fork the specified command.
-D Use dingus clicking: as the cursor moves over text matching a certain pattern, the matched text is highlighted and the cur-
sor changes shape. Disabled by default.
-d Toggle update debugging. Disabled by default.
-f font Specify the font to use. Default font is "Sans 12".
-g Toggle whether to set geometry hints if font is changed. Enabled by default.
-h Toggle highlighting. Disabled by default.
-i Toggle whether to obey attempts to set the icon name, if applications running in the terminal request this.
-k Toggle whether to keep program running after GTK main loop. Disabled by default.
-n Specify the number of scrollback lines. Minumum number of scrollback lines is 100. Default number of scrollback lines is
100.
-r Toggle whether to set cursor color to pale red. Disabled by default.
-S Toggle launching a shell. Enabled by default.
-s Toggle whether to scroll background image along with text. This option is only useful when combined with the -B option.
Disabled by default.
-T Use transparent background. Overrides the -B option.
-t terminal-typeSpecify the terminal type to emulate.
EXTENDED DESCRIPTION
vte is designed to emulate the xterm program provided by the X Consortium. In turn, xterm is an almost complete emulation of the DEC VT102
terminal. vte supports the same extensions to VT102 as those provided by xterm, through special escape sequences.
xterm is an evolving program. Recent changes to xterm have been been incorporated into vte. This includes emulation of the newer DEC VT220
escape sequences.
