Normalize Unicode

[ukretschmer]

As we use authority data derived from entityfacts, which itself serves data from DNB and those data will be served as UTF-8 decomposed, we have to use Java Scripts normalize function to prevent irritating data in users data.

Example: Search for a persons authority data and view it in the tabular view, authority data records can be simply copied to the local dataset. If for example the place of birth is "Düsseldorf" we would get "Düsseldorf" (decomposed, like Culturgraph dataset). Searching für "Düsseldorf" in our exported data would not match the imported place of birth.
