basic character classes not working

[ianlewisau]

I have used Reggy for some time without issue. I have just found that it doesn't seem to interpret "" characters correctly in the regex string. For example "\d" will match "d', but not a digit. Likewise, "\w" will only match a "w" and no other word character. "\" will match "". Other forms of character class, e.g. [0-9], [a-z.-] etc. work fine. Backslash on its own prompts the message "end pattern at escape", so the backslash is being recognised.
