[pmwiki-users] ISO 8859-1 conversion patterns for page names

[Hans]

I tried to add patterns to the $MakePageNamePatterns array,
but failed. Setting $MakePageNamePatterns in config.php resulted in
heaps of errors, and I do not know how to add items or another array
to the $MakePageNamePatterns array. Does it needs to be set with SDVA
in pmwiki.php?

I thought it should be easy to make pagenames for ISO 8859-1 characters
by mapping accented etc characters to their unaccented equivalents,
using a conversion array and adding that to $MakePageNamePatterns.
How can this be done? Has it been done before? This could become a
recipe.

What is the effect on efficiency adding such a bunch of patterns?
MakePageName is called  a lot.

I include a pattern array for ISO 8859-1 underneath (long for easier
reading! Maybe it needs tweaking. Maybe some characters are missing.)
