Basically, is something like
{{ ">>"|escape }}
possible?
I can use {{ context_variable|escape}}
but can I use a string literal?
I want to avoid littering my template files with >
Yes. Django treats invalid variables as an empty string. That's the case when you pass a string literal. I will have the string literal concatenated to an empty string.
There is also this answer here. Literal HTML in Django without using a variable?
