Issue #17110 has been updated by theplen (Joey Sheets).
Is there no way to do change all backslashes to forward slashes and forward slashes to backslashes in the same tr command?
``` ruby
# Should result in "/\\" but instead results in "\\/" (unchanged)
"\\/".tr("\//","\\/")
```

Bug #17110: String.tr unexpected behaviour with backslash

* Author: theplen (Joey Sheets)
* Status: Rejected
* Priority: Normal
* ruby -v: ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x64-mingw32]
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN
----------------------------------------
`"\\".tr("\\","A")` works great, with `"\\"` becoming `"A"`.
`"\\".tr("\\C","AB")` should also output `"A"`, but instead outputs `"\\"`.
