问题 I want to convert normal text to \x codes for e.g \x14\x65\x60 For example : normal text = "base64_decode" converted \x codes for above text = "\x62\141\x73\145\x36\64\x5f\144\x65\143\x6f\144\x65" How to do this? Thanks in advance. 回答1: PHP 5.3 one-liner: echo preg_replace_callback("/./", function($matched) { return '\x'.dechex(ord($matched[0])); }, 'base64_decode'); Outputs \x62\x61\x73\x65\x36\x34\x5f\x64\x65\x63\x6f\x64\x65 回答2: The ord() function gives you the decimal value for a single

问题 I'm making a encryption program and I need to open file in binary mode to access non-ascii and non-printable characters, I need to check if character from a file is letter, number, symbol or unprintable character. That means I have to check 1 by 1 if bytes (when they are decoded to ascii) match any of these characters: {^9,dzEV=Q4ciT+/s};fnq3BFh% #2!k7>YSU<GyD\I]|OC_e.W0M~ua-jR5lv1wA`@8t*xr'K"[P)&b:g$p(mX6Ho?JNZL I think I could encode these characters above to binary and then compare them

Python3: Decode UTF-8 bytes converted as string

问题 Suppose I have something like: a = "Gżegżółka" a = bytes(a, 'utf-8') a = str(a) which returns string in form: b'G\xc5\xbceg\xc5\xbc\xc3\xb3\xc5\x82ka' Now it's send as simple string (I get it as assertion from eval function). How the heck can I now get normal UTF-8 form of starting word? If there is some better compression than str(bytes(x)) then I would be glad to hear. 回答1: If you want to encode and decode text, that's what the encode and decode methods are for: >>> a = "Gżegżółka" >>> b =

How i can encode some elements in MATLAB?

阅读更多关于 How i can encode some elements in MATLAB?

问题 I made two random numbers from 0 to 3. a=0; b=3; A=round(a+(b-a)*rand(1,1000)); B=round(a+(b-a)*rand(1,1000)); then i add every two bits of them. then i convert it to binary. SUM = A + B; binarySum = dec2bin(SUM); because i wanted to count transitions, i write this code: s = 1; for i = 1:1000 for j = 1:3 M(1,s) = binarySum(i,j); s = s+1; end end Tr = sum(diff(M)~=0); now i want to split every 3 elements of M and encode them By another elements. for example 000 By 000000, 110 By 000001, 001 By
