Description

PmWiki changes a character with a macron to a character with a circumflex on save.

See Macron

Problem

A browser or server (not PmWiki) changes a character with a macron to a character with a circumflex on save (see the rightmost column in the table below).

PmWiki doesn't do any such conversions on its own -- there must be some other component that is performing the conversion. I suspect its your browser that is actually changing the characters.

In particular, my browser (Firefox 1.5) is automatically converting "Ā" into Ā prior to sending it to PmWiki.

One thing to note is that that macron characters are outside of the 0-255 codepoint range, so unless a site is using UTF-8 a browser might be very confused and simply try to map things onto ISO-8859-1 (Latin-1, PmWiki's default).

At any rate, I don't think this is a PmWiki bug but is instead a browser bug. What browser are you using?

After more testing it is related to the generation of the macron character, at home I use the Microsoft Mâori keyboard on XP (see language settings), at work it is a a program called Patuhi. Having said all that I have yet to determine how to stop it happening on my wikis, when I find out I'll tell ya.

It's possible that Apache is sending the wrong content-type or character set. I've seen instances where Apache likes to enforce utf-8 on character sets even when the application specifies a different one. Is there a url I could test so that I could see the headers your server is sending back? Perhaps that would provide a clue.

It is quite confusing. Even using the Microsoft Māori language keyboard (eg in this ūpdātē) while the character displays correctly in the text area before submission, it is wrong afterwards - when displayed.

Yes, please try http://ttc.org.nz/pmwiki/pmwiki.php/Test/Macron, unfortunately the site I am having most trouble with is an intranet.
