Log Message: ----------- Improve stripping of whitespace and punctuation characters (fixes #98)
More expensive stripping of whitespace and punctuation characters, including Unicode characters before checking a word. However, this is rather a workaround than a solution. The proper way would be to read words using Scintilla but split a line into words manually with correct handling of Unicode characters.
