unicode - Reading a file in C as utf-8 and iterating through each character? -


how go reading file in c, iterating through each character can evaluate it? instance, give input file of: 5 ≠ 10, evaluate 5 not equal 10, , print out false. can evaluation part, i'm unsure how approach reading unicode characters in c. i'm asking question, since i've written larger lexer, , want have support unicode, wanted try out on smaller-scale project see how goes.

utf-8 encoding format unicode. you're interested in parsing text , separating out each byte. need calculate unicode code point determine character.

ultimately need:

  1. a parser can distinguish utf-8 character boundaries.
  2. a translator convert data encoded utf-8 unicode code point.
  3. and reference list of code points , semantic meanings.

the not equal sign unicode code point u+2260. encoded in utf-8 0xe2 0x89 0xa0.

edit: should using library parsing utf-8 text. should focusing on finding code points relevant application, , interpreting meaning within application.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
