I think you want `"\\"`. See [C syntax - Wikipedia](https://en.wikipedia.org/wiki/C_syntax#Backslash_escapes)

Note also that if your dictionary keys are all single characters, you can use `Char` instead of `String`, i.e. `'='`, `'\\'`, etcetera. Note also that you can have a typed dictionary, e.g. `Dict{String,String}` or `Dict{Char,String}`.

Please provide a minimal working example, with code that can be copied and pasted, as well as describing precisely what you expect to happen.

Please provide a simplified version that everybody can copy and paste to define the variables.

Also, please quote your code using backticks (`)

You must escape the backslash character, as for example `'\\'`. Note there are two backslashes written here, but this is actually a single backslash character.
