PixivUtil2 Filename sanitation didn't work for \

Creating directory: Z:\Visual Media\[Pics]\[Artists]\Pixiv\39318908\R-18\Manga\_161553 18 【睡眠】 起きない子

Didn't sanitize the \. It also placed a _ in the beginning of the filename for some reason?

Latest PixivUtil2 version. Windows 11. NTFS.

When I added \ to the customBadChars setting, I got the following error:

Creating directory: Z:\Visual Media\[Pics]\[Artists]\Pixiv\_39318908_R-18_Manga_161553 18 【睡眠】 起きない子
Error at download_image(): Cannot save https://i.pximg.net/img-original/img/2025/04/23/00/00/52/129597353_p0.jpg to Z:\Visual Media\[Pics]\[Artists]\Pixiv\_39318908_R-18_Manga_161553 18 【睡眠】 起きない子 \ OKINAI KO 129597353 起きない子【女教師】 _ OKINAIKO[teacher] 1.jpg: (<class 'FileNotFoundError'>, FileNotFoundError(2, 'No such file or directory'), <traceback object at 0x000001A8A195BF80>)

It seems to have replaced ALL \ in my filenameMangaFormat, which is:

%member_id%\%R-18%\Manga\%manga_series_id% %manga_series_order% %manga_series_title% %image_id% %title% %page_number%

Even more info further below.

I also encountered the issue with _ in the filename, but no error was shown in the terminal.

Using customBadChars = %pattern<1>(/)%%replace<1>(／)% fixes the two examples above. However, it results in incorrect filenames in both cases: 295867 2 ／_______ 133383142 __ 1.png should be 295867 2 ／_______ 133383142 _／ 1.png 295867 1 ／_______ 133382877 ________ 1.png should be 295867 1 ／_______ 133382877 ／_______ 1.png

Using customBadChars = %pattern<1>(/)%%replace<1>(／)%%pattern<2>(\)%%replace<2>(＼)% breaks the program.

Using customBadChars = %pattern<1>(/)%%replace<1>(／)%%pattern<2>(\\)%%replace<2>(＼)% is broken: it replaces all of the \ in filenameMangaFormat = %member_id%\%R-18%\Manga\%manga_series_id% %manga_series_order% %manga_series_title% %image_id% %title% %page_number%. It also doesn't replace the \ in the filename: Z:\Visual Media\[Pics]\[Artists]\Pixiv\1514277＼Manga＼295867 2 ／_______ 133383142 __ 1.png should be Z:\Visual Media\[Pics]\[Artists]\Pixiv\1514277\Manga\295867 2 ／_______ 133383142 ＼／ 1.png
