This html source throws a Javascript exception. This shouldn't:
<html>
<head>
<script>
reg_exp = /\w|\s|[!-/]|[:-@]|[\[-`]|[{-ÿ]/;
</script>
</head>
<body>
</body>
</html>
The exception throwed is:
Error: unterminated character class [
Source File: file:///C:/tmp/test.html
Line: 4, Column: 15
Source Code:
reg_exp = /\w|\s|[!-/]|[:-@]|[\[-`]|[{-ÿ]/;
This sould work because \[ is escaped

This has nothing to do with the \[. The following throws the same exception:
reg_exp = /[!-/]/;
Escaping the "/" in the character class makes things happy (that is,
reg_exp = /\w|\s|[!-\/]|[:-@]|[\[-`]|[{-ÿ]/;
has no problems).
Looks invalid to me....

Boris is correct. Compare the following:
reg_exp1 = /\w|\s|[!-/]|[:-@]|[\[-`]|[{-ÿ]/;
reg_exp2 = /\w|\s|[!-\/]|[:-@]|[\[-`]|[{-ÿ]/;
In the standalone JS shell:
js> reg_exp1 = /\w|\s|[!-/]|[:-@]|[\[-`]|[{-ÿ]/;
7: unterminated character class [:
7: reg_exp = /\w|\s|[!-/]|[:-@]|[\[-`]|[{-ÿ]/;
7: ..........^
js> reg_exp2 = /\w|\s|[!-\/]|[:-@]|[\[-`]|[{-ÿ]/;
/\w|\s|[!-\/]|[:-@]|[\[-`]|[{-ÿ]/
(WORKS FINE)|
