Mistake in documentation of create_event_file

[MariaHei]

What you were trying to do

I was trying to generate an event file using the pyndl.preprocess.create_event_file function like this

pyndl.preprocess.create_event_file("path/to/input/file.txt", 
    "path/to/output/file.tab.gz", 
    allowed_symbols="*", 
    context_structure="line", event_structure="line",
    cue_structure="word_to_word", verbose=true)

What actually happened

The event file was empty (except cues/toutcomes).

What the problem is

The documentation states here that allowed_symbols="*" is equivalent to allowed_symbols="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ". This seems to be incorrect. The function ran as expected as soon as I changed allowed_symbols to "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ".

System details

Happened both with pyndl from pip and pyndl from github.
