Typeahead: allow ideographic whitespace for token separation

Summary:Allow ideographic whitespace for token separation. This allows users to search for names in CJK languages without switching input modes between words, if searching for multiple tokens.

  児玉 太郎 // worked previously, still works now
  児玉　太郎 // works now, didn't work previously
