Saving A Clean String

How can I go about making sure that no bad or special characters are entered into a string?
Basically I'd like the string to be of ascii characters only or those that can be used in an image filename on the web.
Thanks

hi Jonathan,
If you're using java 1.4+, you can try

In English: "I'm going to describe a String: if my description matches this particular candidate String exactly, then return true, else false.
The description is this: I'd like any sequence of letters, numbers, or underscores, repeated one or more times. Then, I'd like a period. then, I'd like any sequence of letters, numbers, or underscores, repeated one or more times"
HTH,
M
