How to convert a unicode character "\U0001d403" to Escape sequence in python?

Question

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 ?

Answer 1

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.
