Issues with std.regex

[MrAppleseed]

Hey all,

I'm currently trying to port my small toy language I invented 
awhile back in Java to D. However, a main part of my lexical 
analyzer was regular expression matching, which I've been having 
issues with in D. The regex expression in question is as follows:

[ 0-9a-zA-Z.*=+-;()\"\'\[\]<>,{}^#/\\]

This works well enough in Java to produce a series of tokens that 
I could then pass to my parser. But when I tried to port this 
into D, I almost always get an error when using brackets, braces, 
or parenthesis. I've tried several different combinations, have 
looked through the std.regex library reference, have Googled this 
issue, have tested my regular expression in several online-regex 
testers (primarily http://regexpal.com/, and 
http://regexhelper.com/), and have even looked it up in the book, 
"The D Programming Language" (good book, by the way), yet I still 
can't get it working right. Here's the code I've been using:

...
auto tempCont = cast(char[])read(location, fileSize);
string contents = cast(string)tempCont;
auto reg = regex("[ 0-9a-zA-Z.*=+-;()\"\'\[\]<>,{}^#/\\]");
auto m = match(contents, reg);
auto token = m.captures
...

When I try to run the code above, I get:
parser.d(64): Error: undefined escape sequence \[
parser.d(64): Error: undefined escape sequence \]

When I remove the escaped characters (turning my regex into
"[ 0-9a-zA-Z.*=+-;()\"\'[]<>,{}^#/\\]"), I get no issues 
compiling or linking. However, on first run, I get the following 
error (I cut the error short, full error is pasted 
http://pastebin.com/vjMhkx4N):

std.regex.RegexException@/usr/include/dmd/phobos/std/regex.d(1942): 
wrong CodepointSet
Pattern with error: `[ 0-9a-zA-Z.*=+-;()"'[]` <--HERE-- 
`<>,{}^#/\]`

I'm very confused on what to do, and much of the information in 
the library reference seems to contradict what I'm doing. Any 
help would greatly appreciated!

Thanks!
