this is in relation to #52896

I think this
crawledPackageName = crawledPackageName.replaceAll("[^a-zA-Z0-9]+", "")
is bad idea... because you are effectively stripping unicode also. Some package names could be entirely unicode characters. Java regex does not support unicode well, please see http://stackoverflow.com/questions/4304928/unicode-equivalents-for-w-and-b-in-java-regular-expressions (some what of a old thread/question, but I believe still relevant to this day).

my fix to (no) space issue in package names was
crawledPackageName = crawledPackageName.replaceAll("[^a-zA-Z0-9]+", " ").replaceAll("\\s{2,}", " ");
puts spaces in and makes ure there is only one white space char. In the end I also commented out the line because its bad code, for the unicode reasons above.
// crawledPackageName = crawledPackageName.replaceAll("[^a-zA-Z0-9]+", " ").replaceAll("\\s{2,}", " ");
