PDF parsing

Has anyone faced issue with char(0015)? I was trying fetching pdf text from file by splitting with char(0015). However, everything contains 15 in a document file is removed or replaced with blank value. Here is the code I tried for the same.

a!localVariables(

 local!text: getpdftext(document: 32030),

 local!test: a!map(id: "header", value: local!text),

 local!text1: split(

   /*local!test, char(0015)*/

   substitute(local!test, char(13), ""), char(10)

 ),

)
