I’ve noticed that the words in the corpus are formatted with special characters. I’ve figured out that “^” is a replacement for “.” (probably since the latter means “any character” in a regular expression), but I haven’t been able to figure out the rest (e.g. starting with “U:” or “S:”), nor find documentation on this.
What are the special formatting rules for the corpus words? (Adding this to the FAQ, or to the main documentation, would be great…)
