It should take a string like this: ã"37°26â²36.42â³N 06°15â²14.28â³W"ã.

is it faster to replace each one sequentially (i.e. replace first

folks, this one will be interesting one.
the problem is to write a script that can check a dir of text files
(and all subdirs) and reports if a file has any mismatched matching
brackets.
• The files will be utf-8 encoded (unix style line ending).
• If a file has mismatched matching-p
