The text has "Charges" then a variable amount of spaces a previously picked

is this correct or am I missing something? It seems to work sometimes and
not others and I have not quite figured out what makes it fail.
The error I get is
Warning: preg_match_all(): unknown modifier '#' in "file"
Gracious, did you start a long thread. Several workable solutions are provided.
I'd like to offer some general advice, I learned from experience.
I never use "/" as the delimiter; there are too many chances for errors. I generally use "%", unless my haystack can
possible contain it. It is easier to spot syntax errors, for example. Otherwise, I use a delimiter that cannot be in my
haystack and is not a regex reserved character. Rarely is there a delimiter that is both in the haystack and is a
reserved character; if so, I just use literal code "\" as required.
I never use repeated special characters e.g., "\s\s" use "*", "+" or "{n,m}" as needed.
I rarely use "dot all" [e.g., "."] it accepts everything and can make testing very difficult. Invariably, there is a
combination I never thought of to test. I use explicit statements for everything that can be in my haystack [e.g., \d,
\w, [a-z], [0-9], \s, \S, etc.]
I always use the Reg Coach for complicated patterns and build and test the pattern one step at a time.
