merlyn,

I've noticed that CGI::escape is similar to uri_escape and have been using it successfully to avoid using URI::Escape when CGI is already imported. My tests show that CGI::escape also encodes characters like ! and ? that uri_escape leaves alone.

Here's the relevant source code from CGI.pm escape() 

$toencode=~s/([^a-zA-Z0-9_.-])/uc sprintf("%%%02x",ord($1))/eg;

[download]
and here's the code from URI::Escape uri_escape() 
# Build a char->hex map
for (0..255) {
    $escapes{chr($_)} = sprintf("%%%02X", $_);
}
$text =~ s/([^;\/?:@&=+\$,A-Za-z0-9\-_.!~*'()])/$escapes{$1}/g;

My question: Is it safe to use CGI::escape instead of uri_escape?
