unicode recognization is it utf-8 utf-16 or any thing else?

I wish did fix the issue. Why do you have to handle with the encoding? The PostgreSQL JDBC driver should handle it, Java uses UTF-16 internally. So you can simply compare the string got by ResultSet.getString() with any other string or pass any string as parameter if using PreparedStatement.setString().

Is non-unicode the same thing as ASCII?

Date : March 29 2020, 07:55 AM
Any of those help No, it is not the same thing and that's the reason why they didn't just say ASCII. There are many encodings out that are neither Unicode nor ASCII like Windows 1251 also known as CP1251 (cyrillic).

selecting similar values in mysql (some thing, sömé thińg, some-thing, some¤thing should be the same)

I hope this helps . I'm building a tagging system and I need to retrieve similar tags, so when a user would punch in "some thing" or "somé thing" or "söme thing" or "some¤thing" etc he would get all the matching rows in the table. , Yes, the convert :-
code :
mysql> select convert( "söme thing" using utf8) = 
convert( "some thing" using utf8);
| convert( "söme thing" using utf8) = convert( "some thing" using utf8)  |
|                                                                      1 |

Is there such thing as 'Unicode collation'?

By : Marcelo Aruzamén
Date : March 29 2020, 07:55 AM
I wish did fix the issue. Well, there's always a binary collation like Latin1_General_BIN2. It stores the code points in numerical order, which can be pretty arbitrary. It's not culture-specific though (despite the name).
It sounds like there isn't any intelligent way to sort data from multiple languages/cultures together so instead of a half-baked solution, all you can do is sort by the binary values.

Unicode - the right thing to do

wish of those help The most common way is to just throw a meaningful error if the input is not correct and stop.
There are a lot of good reasons to do so:
code :
try {
  q = encode(s);
} catch(encodingerror) {
  t = fixcode(s);
  q = encode(t);

Add gender column recognization

Does that help Use gender() instead of gender_df().
Note that gender() automatically sorts output alphabetically by name, so it won't work to simply add the output as a new vector to demo_df, as the ordering may be wrong.
code :

demo_df %>% 
  arrange(names) %>%
  mutate(gender = gender::gender(demo_df$names)$gender)
gender_df <- gender::gender(demo_df$names) %>% 
  select(names = name, gender)

inner_join(demo_df, gender_df, by = "names")  
  id   names stock bill gender
1  1 Hillary    43   43 female
2  2 Madison     5  112 female
3  3    John     2   33   male
