"return a koelner phonetic code. |

179 |
The koelnerPhonetic code is for the german language what the soundex code is for english; |
|
180 |
it returns simular strings for similar sounding words. |
|
181 |
There are some differences to soundex, though: |
|
182 |
its length is not limited to 4, but depends on the length of the original string; |
|
| 2207 | 183 |
it does not start with the first character of the input. |
184 |
This algorithm is described by Postel 1969" |

There are many extended and enhanced soundex variants around; |
|
517 |
here is one, called 'extended soundex'. It is destribed for example in |
|
518 |
http://www.epidata.dk/documentation.php. |
|
519 |
An author or origin is unknown. |
|
520 |
||
521 |
The number of digits is increased to 5 or 8; |
|
522 |
The first character is not used literally; instead it is encoded like the rest. |
|
523 |
This might have a negative effect on names starting with a vovel, though. |
|
524 |
||
525 |
Overall, it can be doubted if this is really an enhancement after all. |

#' \code{maxCodeLen} is \emph{not} supported in this algorithm encoder

The 'Kölner Phonetik' (cologne phonetic) code is for the german language |
|
3121 |
what the soundex code is for english: |
|
3122 |
it returns similar strings for similar sounding words |
|
3123 |
(but is specifically aware of the pronunciation of German and eastern languages) . |
|
3124 |
||
3125 |
There are some other differences to soundex, though: |
|
3126 |
its length is not limited to 4, but depends on the length of the original string; |
|
3127 |
it does not start with the first character of the input, but returns a pure numeric string. |
|
3128 |
||
3129 |
This algorithm was described by Postel 1969, |
|
