I already try using WorkbookSettings as bellow:

```
WorkbookSettings ws = new WorkbookSettings();
ws.setEncoding("Cp1252");

I belived it is the format the file is. | You can also pass the JXL encoding as parameter for the JVM:

] | Are you sure you need a regex ?
Something like this can calculate the ratio in a row :
```
>>> a = list('abce')
>>> b = list('abcd')
( 100 - (sum(i != j for i, j in zip(key, 'air')) / float(len(a))) * 100 )
75.0
```
But if `b = list('bdce')` it will just be 50% | You may use this alternation based approach:
```
>>> key = 'rain'
>>> l_word = int(len(key) *3 /4)
>>> my_regex = re.compile(r'^' + key[0:l_word] + '|' + key[-l_word:] + '$')
>>> print (my_regex.pattern)
^rai|ain$
>>> print bool(my_regex.search('air'))
False
>>> print bool(my_regex.search('12Qain'))
True
