Yes you are correct. the 2nd colon and the 4 0s are all glitched text. When tmux was started it happened 5:00, so thats what the glitched text was. sorry it is rather unclear. the time is simply "%l:%M in my .tmux.conf
The utf8 underscores were a result of my terminal not supporting utf8, and forcing tmux into unicode mode. When I used a terminal with unicode support (or atleast told my terminal to. I set TERM to rxvt-unicode), then all my characters were displayed again, and the glitches came back and look exactly like the original.
I already have standard numeric scripts for both utilities, and simply parse there output to create the icon characters. You can see from the screenshots how tiny the terminal is, so it is a much more economical use of the space (and looks better and is easier to read) to use the icons, than it would be to use the numeric output with labels.
I am not connecting via ssh. I have a keyboard, and a monitor. havnt needed a mouse on the terminal.
I have tried simply echoing (or printf) the hex or octal values of the characters, or entering and exiting the acs to draw the icons, as well as just pasting them into the script directly and echoing that. the result is the same: the glitch.

Subject: Re: Tmux: echos to the status bar
So in the "standard glitch" picture, what's the actual issue? What should status-right show? I'm guessing the 4 extra zeros in the time aren't desired but…?
The changes you observed with UTF-8 suggest that perhaps whatever you're using to insert the signal and battery glyphs (your script?) isn't escaping the output correctly, leaving data tmux is trying to interpret. These are mapping to gibberish in non-UTF-8 mode and invalid Unicode in UTF-8 mode (hence the underscores).
Check out this script for a text-only tmux battery status script. No suggestions for a wifi signal strength script unfortunately.
Regarding the terminal… are you connecting to the system running wrt using ssh? Connecting over serial from a laptop? Connecting your keyboard & mouse directly to the wrt box? The reason I ask is that if you're connecting with putty or another terminal emulator the terminal settings (particularly UTF-8 and font settings) could be a factor. I don't think so, given the above information though.

I attempted the enabling UTF8, and I thought it actually solved the issue of not displaying the glitched characters, but simply because replaces all my echoed characters as underscores. Once I set TERM to a unicode enabled terminal, everything displayed correctly again, and the glitches came right back. see below. I am running Linux, the openWRT distro to be precise on an embedded system. As for the terminal, I am not entirely sure. They are all virtual ttys I suppose. I have terminfo for rxvt, xterm, rxvt-unicode, xterm-color, linux,dumb, vt100, vt102, and ansi. I am not sure how rxvt or xterm are applicable, because I do not have X. If I had to venture a guess, it is probably FBterm,

>>>For my tmux statusbar, I call some scripts to echo some text to the status right. This however results in some glitched text to the far right side of the statusbar. For each character that is echoed, I get an extra glitched character on the statusbar. The character seems to be whatever was previously ocupying that character before. It is usually my clock, so I will get for example 4:2424 if I echo two characters. If I disable the statusbar, and reenable it, the characters are just orange from the tmux comandline. Attempting to limit the length of the status right only limits the real characters. The glitches are still tacked on the end afterwards.
