Problem with regexp Japanese

Dear all,

I want to find the file paths in the large string by regexp such as:

As you see, pattern search was good in https://www.regextester.com/ . but in Matlab, Japanese string could not get as following:

>>str = ['a:\fawe\abc\AddNew_.doc '...
'C:\Users\Desktop\AddNew\_Copy_新しいフォルダーof_a.txt'];
>>pattern = '(?:[\w]\:|\\)(\\[a-zA-Z_\-\s0-9\u3000-\u303F\u3040-\u309F\u30A0-\u30FF\uFF00-\uFFEF\u4E00-\u9FAF\u2605-\u2606\u2190-\u2195\u203B\.]+)+\.(txt|mat|pdf|doc|docx|xls|xlsx|cgt|slx|m)';
>>match_str = regexp(str, pattern, 'match')


match_str =

  1×1 cell array

    {'a:\fawe\abc\AddNew_.doc'}

Do you have any idea for resolve.

Thank you so much

The \u syntax is not valid in MATLAB:

\u3000 % !!! NOT CORRECT !!!

To create a character from hexadecimal use \x:

\x3000

So you will need to change all of your \u... into \x....

I see.
