SiteMap failure: utf8

I've been tracking down and fixing utf8 "does not map to Unicode" characters in my .txt files. I think I've found them all.

However, my System.SiteMap is giving me an error
Foswiki detected an internal error - please check your Foswiki logs and webserver logs for more information.

utf8 "\xE9" does not map to Unicode

I tracked down the problem down to one line in the SiteMap SEARCH code.

The code contains this line:

  [[%web%.%HOMETOPIC%][%web%]]   

If I change that so the link is not created, i.e.

  %web%.%HOMETOPIC%   

the SiteMap page renders without errors.

I don't see any obvious unexpected characters in any of my web names. But something in the link creation code is dying.

if it helps, the Apache error log contains

From your apache log, it's not E9, it's xAE, which is the registered tradmark symbol ® at least in Windows cp-1252 and iso-8859-1. It might be showing up in a tooltip message for the link depending upon which plugins you have enabled.

-- GeorgeClark - 19 Sep 2015

It turns out that there are several WebHome pages causing the utf8 error, with codes EA, 96, and 9A. (I found the AE).

So, what you're saying is that Foswiki, in building the link, wants to extract info for a totip (http title option) and bumps into a "bad" character...

-- VickiBrown - 19 Sep 2015

Check your setting for LINKTOOLTIPINFO. Default is turned off, but if enabled, it can put various information into a tooltip when a link is generated.

It could also be characters in the WEBSUMMARY setting, which is expanded as part of the SiteMap page.
