Had some newline issues in some data. Might be useful to someone else to have a REPLACE(FIELD, '\n', '') in there as well.

I would really like to tell you all that you are sluggifyin Ðð Þþ Ææ completly wrong

  • Ð -> D
  • ð -> d
  • Þ -> Th
  • þ -> th
  • Æ -> AE
  • æ -> ae

Please fix!
This is actually causing problems for some Icelandic people and tourists visiting Iceland (half of which are from USA) because place names and people's names are being slugified incorrectly.

Read comments after made some fixes for my own purposes... but I think it could be relevant to split the replaces as done here since it will avoid having '_' at the beginning or the end of the slugged string

		), '’', '-'), '\'', '-'), '–', '-'), ' ', '-'), '--', '-'), '--', '-'), 'ñ', 'n'), 'ç', 'c'), 'ø', 'oe'), 'ó', 'o'), 'ô', 'o'), 'ö', 'o'), 'î', 'i'), 'í', 'i'), 'ï', 'i'), 'ú', 'u'), 'ü', 'u'), 'û', 'u'), 'ù', 'u'), 'ý', 'y'), 'ë', 'e'), 'ê', 'e'), 'é', 'e'), 'è', 'e'), 'å', 'a'), 'â', 'a'), 'ä', 'a'), 'á', 'a'), 'à', 'a'), 'ã', 'a'), '²', '2'), '³', '3'), 'æ', 'ae'), 'œ', 'oe'), 'ḥ', 'h')

Let me know if it's useful for you

Forgot to mention a useful thing:

If you search for rows with slugged issues, you can use

WHERE rowName <> CONVERT(rowName USING ASCII)
