파이썬에서 문자의 유니 코드 블록

Question

파이썬에서 문자의 유니 코드 블록을 가져 오는 방법이 있습니까? unicodedata 모듈은 내가 필요로하는 것 같지 않고 외부 라이브러리를 찾을 수 없습니다.

기본적으로 java에는 Character.UnicodeBlock.of()과 동일한 기능이 필요합니다.

Answer 1

하나를 찾을 수 없습니다. 이상한!

다행히도 유니 코드 블록의 수는 상당히 작습니다.

이 구현은 unicodedata의 함수처럼 1 자 유니 코드 문자열을 허용합니다. 입력 내용이 대부분 ASCII 인 경우이 선형 검색은 bisect 등을 사용하는 이진 검색보다 빠를 수도 있습니다. 내가 파이썬 표준 라이브러리에 포함이 제출 된 경우에, 나는 아마 C.

def block(ch): 
    ''' 
    Return the Unicode block name for ch, or None if ch has no block. 

    >>> block(u'a') 
    'Basic Latin' 
    >>> block(unichr(0x0b80)) 
    'Tamil' 
    >>> block(unichr(0xe0080)) 

    ''' 

    assert isinstance(ch, unicode) and len(ch) == 1, repr(ch) 
    cp = ord(ch) 
    for start, end, name in _blocks: 
    if start <= cp <= end: 
     return name 

def _initBlocks(text): 
    global _blocks 
    _blocks = [] 
    import re 
    pattern = re.compile(r'([0-9A-F]+)\.\.([0-9A-F]+);\ (\S.*\S)') 
    for line in text.splitlines(): 
    m = pattern.match(line) 
    if m: 
     start, end, name = m.groups() 
     _blocks.append((int(start, 16), int(end, 16), name))

Answer 2

unicodedata.name (CHR)에서 정적으로 초기화 struct의 배열을 통해 이진 검색으로 써서
