My page often shows things like ë, Ã, ì, ù, à in place of normal characters. I use utf8 for header page and MySQL encode. How does this happen? You need to add more context. Where do these characters show up, what encoding are your tables in, what does the code look like to retrieve the data....
If you want any of these characters displayed in HTML, you can use the HTML entity found in the table below. If the character does not have an HTML entity, you can use the decimal (dec) or hexadecimal (hex) reference. These control characters were originally designed to control hardware devices.
In my case, I had an even more severely garbled MySQL table where "é" had become "ÃÆ'©", "è" had become "ÃÆ'¨", etc. I first had to convert that using the query shown here: https://stackoverflow.com/a/74092827/3018750 , and then convert that down using your conversion table.
In Portuguese there are some signals that maybe may confuse us. This post is dedicated to get this confusions over! O que está em parênteses é o sinal sozinho, sem estar sobre uma letra e o que vem antes dele é como chamamos este sinal.
〠㠊å¾Â... (3) The kicker is, I can undo from (2) to (1) using PHP's utf8_decode, and I can undo from (3) to (2) using Mysql/PHP's Mysqli (either by using MySQL's CONVERT and BINARY in combination, or by setting PHP's Mysqli charset to latin1 and fetching the UTF-8 column)...
UTF-8 covers almost all of the characters and symbols in the world! Full UTF-8 Reference. ASCII was the first character encoding standard for the web. It defined 128 different characters that could be used on the internet: Special characters like ! $ + - ( ) @ < >. ANSI (Windows-1252) was the original Windows character set:
U+00C3 is the unicode hex value of the character Latin Capital Letter A with Tilde. Char U+00C3, Encodings, HTML Entitys:Ã,Ã,Ã, UTF-8 (hex), UTF-16 (hex), UTF-32 (hex)
When using just the character "a", the correct is "à". The pronunciation is practically the same as "o" in "ouch". 2. "ã and a" are the same and are practically the same as "un" in "under". When used as a letter, "a" has the same pronunciation as "à". Again, just "ã" does not exist. 3. "â" is the same as "ã". Again, just â" does not exist.
So, when looking at UTF-8 encodings of Latin-1 characters, if you see  or à where you do not expect it, there are probably too many UTF-8 encodings. Multiple extra encodings have a pattern to them:
It appears to replace contractions and possessive ' I get this strange combination of characters In my emails replacing '. Why? â€Â. That's a sign that the message uses a different character encoding than you are using in Outlook. For example, the message is encoded in UTF-8 but Outlook is set to use ISO-8859-1.
