In the below string I'm supposed to read the value from ` (opening single quote - ASCII value 96) until └. I couldn't figure out how to come up with a regex for this case - errors due to alphanumeric and numeric conditions. Please HELP!

Actual string:
str="00└9a00└9g00└9`000└9a00└9e000└9a00└9`000└9a00└9e000└9a00└9`000└9a00└9e000└9a00└9`000└9a";
Data to be read: between ` and └.
U+2514, one of the box-drawing characters.
