Regexp to match all characters including "?"

Regexp to match all characters including "?"
Hi everyone,
I'm almost tearing my hairs to find a valid regexp which will match EVERY character in a string, including the question mark!
Specifically I need to match a string which contains the word (example) "stringtobematched" at the end of it.
Everyone would suggest this:
^(.*)stringtobematched$
This obviously works, but it stops working if I introduce the question mark (?) character at any point before the matching pattern.
For example:
blablabla?blastringtobematched
..will not be matched!
It looks like that the "." (dot) character doesn't match the question mark.
Is there a regexp which matches every characters question marks included? (not necessarily matching only strings with question marks, but optionally)
I've tried something like this:
(.*)[\?](.*)blastringtobematched?
But it didn't work
Any help?
Thanks!
PS: regexp being used from Apache's mod_rewrite. Writing in this forum because after all regexp's are still considered part of shell scripting. Apologies in case I was wrong!

ppi::token::regexp5.18
PPI::Token::Regexp(3) User Contributed Perl Documentation PPI::Token::Regexp(3) NAME
PPI::Token::Regexp - Regular expression abstract base class INHERITANCE
PPI::Token::Regexp isa PPI::Token isa PPI::Element DESCRIPTION
The "PPI::Token::Regexp" class is never instantiated, and simply provides a common abstract base class for the three regular expression classes. These being: m// - PPI::Token::Regexp::Match s/// - PPI::Token::Regexp::Substitute tr/// - PPI::Token::Regexp::Transliterate The names are hopefully obvious enough not to have to explain what each class is. See their pages for more details. To save some confusion, it's worth pointing out here that "qr//" is not a regular expression (which PPI takes to mean something that will actually examine or modify a string), but rather a quote-like operator that acts as a constructor for compiled Regexp objects. METHODS
The following methods are inherited by this class' offspring: get_match_string The "get_match_string" method returns the portion of the regexp that performs the match. get_substitute_string The "get_substitute_string" method returns the portion of the regexp that is substituted for the match, if any. If the regexp does not substitute, "undef" is returned. get_modifiers The "get_modifiers" method returns the modifiers of the regexp. get_delimiters The "get_delimiters" method returns the delimiters of the regexp as an array. The first element is the delimiters of the match string, and the second element (if any) is the delimiters of the substitute string (if any). SUPPORT
