问题
Making some Bookmarklet, I tried to use JavaScript minifier like Google Closure Compiler or YUI Compressor. However, I didn't use these because they replace every single quotes with double quotes. I can't use a code which has double quotes, as I should enclose the code with double quotes like:
<a href="javascript:alert('hello')">hello</a>
So, I used MinifyJavascript for minifying. I wonder why other minifiers replace quotes. Replacing quotes doesn't minify codes. Coding style is not important for minified code. Then what is the reason for this?

Pure speculation in this answer:
- Enforce style consistency.
- Consistency reduces size when gzip'ed, because of repeating character sequences.
Can't really think of anything else. They could have chosen single quotes instead of double, though.
