List of unicode character names

问题

In Python I can print a unicode character by name (e.g. print(u'\N{snowman}')). Is there a way I get get a list of all valid names?

回答1:

Every codepoint has a name, so you are effectively asking for the Unicode standard list of codepoint names (as well as the *list of name aliases, supported by Python 3.3 and up).

Each Python version supports a specific version of the Unicode standard; the unicodedata.unidata_version attribute tells you which one for a given Python runtime. The above links lead to the latest published Unicode version, replace UCD/latest in the URLs with the value of unicodedata.unidata_version for your Python version.

Per codepoint, the unicodedata.name() function can tell you the official name, and unicodedata.lookup() gives you the inverse (name to codepoint).

If you want a list of all unicode character names, consider downloading the Unicode Character Database.

It is included in the base repositories of many linux distributions (ex. "unicode-ucd" on RHEL).

The package includes NamesList.txt, which contains the exhaustive list of unicode character names.

Caution: NamesList.txt need some times to be downloaded (size > 1.5 MB).

Example:

回答3:

Yes there is a way. Going through all existing code points and calling unicodedata.name() on each of them. Like this:

names = []
for c in range(0, 0x10FFFF + 1):
    try:
        names.append(unicodedata.name(c))
    except KeyError:
        pass
# Do something with names

回答4:

For a given codepoint, you can use unicodedata.name. To get them all, you can work through all the billions to see which have such names.

If you want to insert a unicode character by name, but don't know the name. Here is how you get an easy overview of unicode character names.

On Windows

Open "Character Map" (search for charmap.exe and run it).
Select any common Microsoft font (these tend to have a wide variety of unicode characters defined).
Click on any character on the map to get its Unicode Character Name.

On Mac it's called "Character Palette" and found under System Preferences, "International -> Input" or "Language & Text -> Input Sources" by ticking the box next to "Character Palette".

Just print them all:

import unicodedata 

for i in range(0x110000): 
    character = chr(i) 
    name = unicodedata.name(character, "") 
    if len(name) > 0: 
        print(f"{i:6} | 0x{i:04X} | {character} | {name}")

回答7:

my one liner, just for my own reference ;p

import unicodedata
names = [unicodedata.name(chr(c)) for c in range(0, 0x10FFFF+1) if unicodedata.name(chr(c), None)]
