Okay... I have been useing Slackware for a while now. I have always had this strange problem with the letters, today I am just in a bad mood, so I decided to do something about it. The characters are replaced with strange little boxes with letters and numbers inside them... Very bizare. This is in all the programs I use... text editors IRC clients and Mozilla. I am useing Fluxbox as my WM, but it happens in KDE and GNOME aswell... basically in all of them. I don't know if this is a common problem with Slackware or if it is fixable... Please, someone help me.

What - even in the text editors? ALL the characters in the set or just the 52 letter characters (26 upper and 26 lower case) You expect *some* effects like that when you type characters that are not in the charater set used or otherwise not supported... but that shouldn't be your problem (unless you have neglected to install character sets - fonts...)
I've only seen this using vim to read .txt files for the star wars screensaver.

Well... It is only with strange characters... Not all letters. For example... the German letter for the double S sound will be a box with the numbers in it... The Euro sign (money) will come out to be a strange thing too.

About the installing of character sets... I have a full install of Slackware 9.1. Do I have to install these things seperately or something?

Well - whenever I try to write a funny character when the font doesn't support it, it usually writes a box in wysiwyg editors and a ? in text only. I bet accented characters come out the same too?

What are you doing to type a special character... does it do this in a "sybmol" style font?

Every Russian character is replaced by this little box with numbers. How do I install new fonts to my system so that the Russian characters will be shown in all apps?

Slackware is somewhat alien to me - I can only offer generic advice vis:

man font (font manual page)
apropos font (gives you a list of terminal commands with descriptions to try using man or *--help on... otherwise you should look gor a font manager in your gui under preferences or settings or similar.)

if you have a wysiwyg editor, it's help pages may be - um - helpful... at least as to installing fonts for that app. And, anyway, it will tell you exactly what fonts are on your system.

I suspect that all you need to do is copy the font to the shared font directory - wherever it is in your system... look for files like *.ttf and other font formats supported by your system, lots of them together is probably the right place.
