Creating an issue to track the inconsistent support of escape sequences as mentioned here: #97 (comment)

A list of escape sequences for regular strings are listed at:

A list of extra escape sequences for template strings are mentioned at the bottom of:

A possible fix could be https://github.com/iansan5653/unraw (or at least it might be useful to draw inspiration from)
