Issue with Keyboard or Char Encoding During Migration

There is a minor issue lingering which we currently have no working solution.

For example, see this pagetext in the original (old) forum mysql DB (continued thats to hicksd8 for finding these and for looking into this interesting topic):

Issue with Keyboard or Char Encoding During Migration-screen-shot-2020-04-28-92934-amjpg


From original DB:

Code:
| Hi have two directory with below name in “/opt“

1-Source
2-Destination 

In “Source” directory there is a lot’s of files, with extensions (doc, docx , ppt, xls,...).
In “Destination” directory only pdf version of (doc, docx) files that exist in source stored.

Now I want to create script that use “diff” command check “source” and get list of only (doc, docx) files after that look for related pdf file in “Destination” if pdf version of (doc, docx) not exist in “destination” store list of them on a file.

E.g.

1-Source
[CODE]File1.doc
File2.docx
File3.doc
File4.ppt
File5.xls
File6.doc[/CODE]

2-Destination 
[CODE]File1.pdf
File3.pdf
[/CODE]

Expected result after run script is:
[CODE]File2.docx
File6.doc[/CODE]

Here is my script
[CODE]diff -r “/opt/source” “/opt/destination“[/CODE]


Any recommendation?
Thanks



UPDATE 
Follow below post and work like charm:

[CODE]comm -23 <(find dir1 -type f -exec bash -c 'basename "${0%.*}"' {} \; | sort) <(find dir2 -type f -exec bash -c 'basename "${0%.*}"' {} \; | sort)
test1[/CODE]

Here is the migrated post:

Note that some of the strange chars in the original DB become the "unknown unicode char" \uFFFD in the new DB:

This encoding issue is very noticeable in spam in our database (mostly from non-English speakers and countries).

We see this occasionally in the DB from other non-English speakers and do not have a perfect solution for this issue, so far.

Here some clues about this:

mysql - Trouble with UTF-8 characters; what I see is not what I stored - Stack Overflow

https://stackoverflow.com/questions/...-utf-8characte

Some suggest code like this:


Code:
$final = str_replace("Â", "", $final);
$final = str_replace("’", "'", $final);
$final = str_replace("“", '"', $final);
$final = str_replace('â€', '-', $final);
$final = str_replace('â€', '"', $final);

I will try this on staging server today.

Note: Actually, this kinda' fun in a perverted kinda' way. LOL

After this test, I may give this ruby gem a try as well:

File: README - Documentation for mojibake (1.1.2)

Quote:
Mojibake occurs in English most frequently due to misinterpreting and bad-transcoding between Windows-1252, ISO-8859-1, and UTF-8. This module provides a mojibake sequence to original character mapping table, and utility to recover mojibake'd text. Testing has been with English but other Latin based languages, where Windows-1252 is in the wild, should also benefit.

FYI existing old mysql dB

Code:
mysql> SELECT count(postid)  from post where pagetext like '%“%';
+---------------+
| count(postid) |
+---------------+
|            66 |
+---------------+
1 row in set (1.64 sec)

mysql> SELECT count(postid)  from post where pagetext like  '%†%';
+---------------+

1 row in set (1.68 sec)


mysql> SELECT count(postid)  from post where pagetext like '%â€%';

1 row in set (1.66 sec)

+---------------+
| count(postid) |
+---------------+
|           165 |
+---------------+
1 row in set (1.63 sec)

mysql> SELECT count(postid)  from post where pagetext like '%‘%';                                                                                                                    
+---------------+
| count(postid) |
+---------------+
|            38 |
+---------------+
1 row in set (1.69 sec)


mysql> SELECT count(postid)  from post where pagetext like '%•%';
+---------------+
| count(postid) |
+---------------+
|             4 |
+---------------+
1 row in set (1.70 sec)

mysql> SELECT count(postid)  from post where pagetext like '%…%';
+---------------+
| count(postid) |
+---------------+
|            23 |
+---------------+
1 row in set (1.68 sec)

Now that SELECT shows some goodies, maybe UPDATE on main DB ? Smilie
