No. You're inside double quotes, so you parse the content accordingly.
Inside double quotes, $ may begin a parameter expansion, or an
arithmetic expansion, and so on. But in this case, it does not.
So the $ is just taken literally.
If you want to use something that expands to a tab inside double quotes,
try this:
tab=$'\t'
echo "$tab " | xod
echo "${tab}indented" | xod
