Hi @Sudhakar，
Try putting extra apostrophe and replace ' with ". In your case the url should be like following
https://<Site_URL>/_api/web/GetFileByServerRelativeUrl("/SudDammyDocLib/DocLib_Folder/issue''s.aspx")/$value

Hello @RaytheonXie_MSFT ,
Thank you for the response, after adding the one extra single quate (') I'm able to fetch the response but wanted to know why we have to add extra single quate?
Does Microsoft SharePoint documented this limitation? If yes then could you please share the reference of it.
Thank you
Hi @Sudhakar，
Certain characters have reserved meanings in programming syntax. Escape characters allow you to use them literally. In the api https://<Site_URL>/_api/web/GetFileByServerRelativeUrl('/SudDammyDocLib/DocLib_Folder/``issue's.aspx``')/$value
The api will only read to the second ' and it ends as /SudDammyDocLib/DocLib_Folder/issue. So we need to use '' to escape characters and the api will get /SudDammyDocLib/DocLib_Folder/``issue's.aspx as expected.
Hi @Sudhakar，
Would you please provide us with an update on the status of your issue?
