  +==== Options
  +
  +[horizontal]
  +`strength`::
  +    The strength property determines the minimum level of difference considered significant during comparison.
  +     The default strength for the Collator is `tertiary`, unless specified otherwise by the locale used to create the Collator.
  +     Possible values: `primary`, `secondary`, `tertiary`, `quaternary` or `identical`.
  + +
  + See http://icu-project.org/apiref/icu4j/com/ibm/icu/text/Collator.html[ICU Collation] documentation for a more detailed
  + explanation for the specific values.
  +
  +`decomposition`::
  +    Possible values: `no` or `canonical`. Defaults to `no`. Setting this decomposition property with
  +    `canonical` allows the Collator to handle un-normalized text properly, producing the same results as if the text were
  +    normalized. If `no` is set, it is the user's responsibility to insure that all text is already in the appropriate form
  +    before a comparison or before getting a CollationKey. Adjusting decomposition mode allows the user to select between
  +    faster and more complete collation behavior. Since a great many of the world's languages do not require text
  +    normalization, most locales set `no` as the default decomposition mode.
  +
  +[float]
  +==== Expert options:
  +
  +[horizontal]
  +`alternate`::
  +     Possible values: `shifted` or `non-ignorable`. Sets the alternate handling for strength `quaternary`
  +     to be either shifted or non-ignorable. What boils down to ignoring punctuation and whitespace.
  +
  +`caseLevel`::
  +    Possible values: `true` or `false`. Default is `false`. Whether case level sorting is required. When
  +     strength is set to `primary` this will ignore accent differences.
  +
  +`caseFirst`::
  +    Possible values: `lower` or `upper`. Useful to control which case is sorted first when case is not ignored
  +    for strength `tertiary`.
  +
  +`numeric`::
  +    Possible values: `true` or `false`. Whether digits are sorted according to numeric representation. For
  +    example the value `egg-9` is sorted before the value `egg-21`. Defaults to `false`.
  +
  +`variableTop`::
  +    Single character or contraction. Controls what is variable for `alternate`.
  +
  +`hiraganaQuaternaryMode`::
  +    Possible values: `true` or `false`. Defaults to `false`. Distinguishing between Katakana and
  +    Hiragana characters in `quaternary` strength .

  The Following example excempt Swedish characters from the folding. Note
  that the filtered characters are NOT lowercased which is why we add that
  filter below.
  
  
negative.code: === ICU Folding
  
  Folding of unicode characters based on `UTR#30`. It registers itself
  under `icu_folding` and `icuFolding` names.
  The filter also does lowercasing, which means the lowercase filter can
  normally be left out. Sample setting:
