It would seem abcÑdef is a valid Windows filename, but does not match the regular expression above. The middle character here is from ISO/IEC 8859-1 (00D1/209).

Just reduce the max size by a few and demand a suffix/extension:
\.[a-z]{1,5}
Who saves filenames that long?!

Comment:
Names starting with a period (e.g. .htaccess, .jpi_cache) are valid names under Windows. Although explorer won't let you rename a file to start with a period, other programs can save them as such, and you can manipulate the files without any problem.

Comment:
Allows input that begins with leading or trailing spaces which are not valid windows filenames. Also allows the input to trail with period which is also invalid.
