Re: [Phpwiki-talk] Problem with big archives

[Sébastien Le C. <sl...@ya...>]

I've finally been able to import all my pages!!

The last hurdle was that I was trying to export iso-8859-1 pages and 
import them into a utf-8 phpwiki setup: all the pages with non-ASCII 
characters were not being imported because the pagename was not 
converted into utf-8 after the urldecode when importing.  A quick change 
to force the pagename to utf-8, and that's it!

One remaining question, though (probably a FAQ, actually): is there a 
way of not importing the PhpWiki “core” pages?  When exporting, I 
usually do a full dump, which contains PhpWikiAdministration and all the 
Help pages, etc. but I don't to import them back, as I may be losing the 
changes done to these pages as part of the upgrade.

Any obvious way of achieving this?

Thanks,
Seb
