…ght, append_trailing_char_if_absent (#49127)
The url_encode function previously performed a modulus operation on a
signed number. Converting it to an unsigned number will fix the issue.
```
before
mysql> select url_encode('编码');
+----------------------+
| url_encode('编码') |
+----------------------+
| %5.%23%0-%5.%10%/( |
+----------------------+
now
mysql> select url_encode('编码');
+----------------------+
| url_encode('编码') |
+----------------------+
| %E7%BC%96%E7%A0%81 |
+----------------------+
```
The strright function did not calculate the length according to the
number of UTF-8 characters.
```
before
mysql> select strright("你好世界",5);
+----------------------------+
| strright("你好世界",5) |
+----------------------------+
| |
+----------------------------+
now
mysql> select strright("你好世界",5);
+----------------------------+
| strright("你好世界",5) |
+----------------------------+
| 你好世界 |
+----------------------------+
```
he case of inputting a UTF-8 character was not considered.
```
mysql> select append_trailing_char_if_absent('中文', '文');
+-------------------------------------------------+
| append_trailing_char_if_absent('中文', '文') |
+-------------------------------------------------+
| NULL |
+-------------------------------------------------+
now
mysql> select append_trailing_char_if_absent('中文', '文');
+-------------------------------------------------+
| append_trailing_char_if_absent('中文', '文') |
+-------------------------------------------------+
| 中文 |
+-------------------------------------------------+
