home / issues / issue #10

Issue:Page displays square boxes or incorrect characters in place of valid characters
Browser:Netscape 4.x
Platform:All platforms
Description:After HM menus are created on a page, Netscape 4 reverts the existing characters on the page to square boxes or other illegible characters. This is triggered by a page "redraw," and is typically intensified by scrolling the page.
Cause:This is a known and somewhat infamous problem when layers are written to dynamically via JavaScript (the technique used in HM for NS4.x) on pages which utilize utf-8 encoding. When using server-side page delivery methods such as ASP or PHP, note that the character encoding for the page may be set by the server-side scripting engine in the page header delivered to the browser; prompting some folks to note that the problem "goes away" when they deliver their pages as .html pages instead of .php or .asp (or .aspx). Typically, the real change is that the script page is being sent with a different character encoding identifier than the .html page.
Comments:Unfortunately this is a bug in NS4.x DHTML that we have no work-around for--other than to change your character encoding designation on the page (or in your server-side scripting environment). MS has posted one tip for the problem that you may find of interest (especially for ASP environments) here:
