It is a Mathematical Alphanumeric Symbols ( capital D ) and I just want to convert into simple English letter ( Capital D ).

Like, \U0001d403 => \uxxxx.

I am not familiar with decode-encoding mechanism.

Is there any conversion way ?

  • Could you maybe further clarify your question. since running print('\U0001d403') gives the Capital D Commented Jun 4, 2021 at 13:32
  • The escape sequence is only useful in string literals. If you already have a str value, you probably just want a new string with the correct character already in it. Commented Jun 4, 2021 at 13:34
  • If you are looking for a way to convert this symbol into a normal capital D, you can do import unicodedata and then unicodedata.normalize('NFKC', '\U0001d403') results in 'D'. Commented Jun 4, 2021 at 13:37

If nothing else, you can build your own map for the string translation: for example:

>>> x = '\U0001d403' >>> x '𝐃' >>> x.translate(str.maketrans({'\U0001d403': 'D'})) 'D'

maketrans can create a mapping of multiple characters, which can be saved to be reused as an argument for many calls to str.translate. Note also that str.translate works for arbitrary strings; the given map will be applied to each character separately.
