B4A Class [Fix - Class] Proper Case For Names

First of all, a thank you @stevel05 for sharing an interesting source of this class.
I took the liberty of placing a slight correction in the indicated place,
which eliminates the error on line: 67 (Proper) - see original class.
The fix in this form will handle one event omitted by the author, namely:
- when the length of the Word variable is zero.
In my case it works for now...

Error occurred on line: 67 (Proper)
java.lang.StringIndexOutOfBoundsException: String index out of range: 1
at java.lang.String.substring(String.java:1963)
....
