I usually rely on regex to remove the redundancy. Julia has built-in regex support in case you know how to use it:
match(r"T[-0]*\d+", label)
If you are not familiar with regex syntax, you can take a look at:
https://github.com/jkrumbiegel/ReadableRegex.jl
Finally, there is
https://github.com/matthieugomez/StringDistances.jl
for distances between strings.
