[julia-users] Re: parse Unicode string to Float64

This is rather odd, your character codes are control codes (0x02 STX, start of text; 0x05 ENQ, enquiry) and really do not belong in a numeric string. Do all the entries use that pattern "\x002\anumber.\x005\bnumber"? If so, and the intended number is anumber.bnumber, there would be a way. What

[julia-users] parse Unicode string to Float64

I'm trying to parse a text file which contains some floating point numbers. The number 2.5 is represented by the string "\x002\0.\x005\0". Parse will not convert this to a Float64. Print works (prints "2.5") in Atom and Jupyter, but not in the REPL. _ _ _ _(_)_ | A fresh approach
