Hello everyone


I now have a a.txt file, the content is \u5171\u7528, after using the fileread() function to read, I want to convert \uxxxx into corresponding characters, the following is my attempt

li_fhandl=fileopen("C:\work\a.txt")
li_fread=fileread(li_fhandl, ls_line)
lbl_data = Blob(ls_line, EncodingUTF8!)
ls_str = String(ls_line, EncodingUTF8!)
messagebox("", ls_str)

 

\u5171\u7528 is displayed in the pop-up, because \u5171\u7528 is always treated as a string instead of a unicode, I tried to search for decode in https://docs.appeon.com/pb2019r3/powerscript_reference/ and did not find a suitable function


Is there any function to solve this problem?

You can use the HexDecode function of coderobject for this. Sample:

coderobject code
blob lblb_uni
string ls_uni
ls_uni = 'u\5171\u7528'

code = create coderobject
lblb_uni = code.hexdecode( ls_uni )
messagebox( 'Uni', string(lblb_uni, EncodingUTF16BE!) )

Do a search in the PB help on "Coderobject", maybe it will have a function that you can use for your purpose?

regards.
