Is is necessary to keep '\' as escape characters to indicate '_' in somr URLs?

[chnln]

When fetching titles from some URLs like those from Bilibili.com, some backslashes will be added automatically. Then the titles will be separated into several segments when the cursor is on them. For example, when pasting https://www.bilibili.com/video/BV1bW411n7fY, the title will be 【春晚鬼畜】赵本山：我就是念诗之王！【改革春风吹满地】_哔哩哔哩_bilibili.

I am wondering whether it is recommended to keep these backslashes since after I deleted them, the title became a whole string again and it functions well.
