187676 - huge empty space in page when character coding set to ISO-8859-1 but is fixed with UTF-8

Status: RESOLVED DUPLICATE of bug 113779

(Core :: Layout, defect)

Description

[Petrus Lundqvist]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3b) Gecko/20030103

Lately with the nightly builds, I've experienced some web pages having huge
gaps. These have especially been on finnish language sites, which led me to try
out something. I changed the character coding to UTF-8, which causes the finnish
characters to be rendered wrong, but it indeed fixed the layout issue and the
huge gaps are gone. Apparerntly, the height of the finnish characters (that
aren't using in the english alphabet) are reported wrong or something, and it
causes huge vertical caps in pages.

This is always reproducable when it happens once, but the particular site I'm
reporting is dynamic and changes once per hour as the weather report changes, so
it might not show up with some particular settup. Right now, for example, it is
100% reproducable, however. It also happens so much with other Finnish language
sites that another test case should be easy to produce if necessary.

Reproducible: Sometimes

Steps to Reproduce:
1. Set character encoding to ISO-8859-1
2. Go to http://www.fmi.fi/saa/paikalli.html?kunta=Helsinki
3. Notice how below "lämpötila" there's a huge vertical gap


Actual Results:  
Huge vertical gap below the word "lämpötila".

Expected Results:  
Correctly rendered page.

Attached two screenshots. One with the correct layout, one with the incorrect.
Notice the vertical scrollbars and gaps below the word "lämpötila".

With 1.2.1 (pretty old, but no other one around) on Win95 (the same about
this...) it works for me at the moment (which does not necessarily mean anything
since I can remember I also saw something similar from time to time (but not
very often).

Bug 130675 and bug 138419 sound similar.
