Your browser should have some sort of controls for handling fonts. There are limits to what you can do, but a few very basic settings should be "somewhere" in any browser.

In IE, Tools|Internet Options, on the General tab, should have a "Fonts" button near the bottom. You can specify what "Language" you want to use, and which font you want used for html pages and which to use for plain text.

It's usual to specify a "proportional" font for html, and a "monospace" for plain text.

Verdana is a "preferred" proportional font (by Microsoft) and should be present on nearly all computers. It could be a good choice, and on some computers it may have more "international" characters than some older ones you may have. "Times family" and Arial are other popular proportional ones. Courier and a number of others are often used for monospaced. What you specify here must be a font that you have on your own computer.

Also at the Tools|Internet Options, General Tab, Fonts Button, in IE, there should be a "link" to "How to Ignore Preset Fonts." This just takes you to the "Accessibility" settings where you can make choices for three things to ignore if someone specifies a font on a page you look at.

A font called in "code" in the page html, as has been done for a few "examples" above in this thread, will be displayed only if the font is on your machine.

A web site can embed a font that you don't have, so that it "sends with the page." The most common(?) usage of this is by companies who have created their own font for displaying corporate (©) names, logos, and icons, although it does pop up occasionally for less "formal" purposes.

When/if people specify a font in a post here, it should be remembered that people who bought their computers in different parts of the world do not have the same default fonts as when the same computer with the same OS is acquired elsewhere, and quite probably don't even have the same keys in the same places on their keyboards. Using the "skill" you may have to call for unusual fonts may make your message illegible for some users, in addition to the usual "incomprehensible" character associated naturally with some who are prone to such use.
