Are you wrestling with a digital enigma, a cryptic language of symbols that renders your text unreadable? The frustrating phenomenon of "mojibake," where intended characters are replaced by a jumbled mess, is a surprisingly common issue plaguing digital documents and web content across the globe.
The root of the problem often lies in character encoding, the system used to translate human-readable characters into the binary language computers understand. When a document or website is created using one encoding, but then displayed or interpreted using a different one, the characters can become corrupted. For instance, you might see strings of seemingly random characters, such as "\u00c2\u20ac\u00a2 \u00e2\u20ac\u0153 and \u00e2\u20ac," instead of the intended characters. This can manifest in various forms, including the dreaded appearance of Latin characters where they shouldn't be, starting with sequences like "\u00e3" or "\u00e2".
| Problem | Details | Possible Causes | Solutions |
|---|---|---|---|
| Mojibake in Database Tables | Strange characters present in about 40% of database tables, not just product specific tables. | Incorrect character set in database settings. Mismatch between the encoding used for data entry and the database's configured encoding. |
|
| Mojibake on Website Front-End | Combinations of strange characters inside product text and other web content. | Incorrect character set declaration in the HTML section. The web server not serving the correct encoding. |
|
| Importing Text from External Sources | Problems can occur when importing text from external sources, which may use different character encodings. | Mismatch between the encoding of the source file and the program importing it. |

The problem scenarios include the appearance of multiple extra encodings, as well as the conversion of characters into unexpected or incorrect forms. You might face eightfold/octuple mojibake, a case that can be illustrated by Python. For instance: P \u00e1 \u00f0m\u00e2 \u00e3\u00a8 \u00e3\u00b4 g\u00e1 \u00e3 \u00e5 g\u00e2 @\u00e3 \u00e5\u00f4 \u00e3 \u00e5 @\u00e3( \u00e3 \u00e5@ \u00e3 @\u00e3 ; The root causes can range from incorrect database settings to issues with web server configurations or improperly defined character sets in HTML code.
Consider the scenario where the front end of a website is riddled with strange characters within product descriptions, where you might encounter characters such as "\u00c3, \u00e3, \u00a2, \u00e2\u201a \u20ac, etc." These characters can be found in a substantial portion of database tables, not limited to product-specific tables. The core issue here is that the system fails to correctly interpret the character encoding used to store the data.
When we see that "\u00c3" and "a" are the same in this case, it's practically the same as "un" in "under". For example, when "a" is used as a letter, it can have the same pronunciation as "\u00e0". Often, just "\u00e3" doesn't exist. Similarly, "\u00c2" is equivalent to "\u00e3". The important thing to remember is that the meaning and pronunciation of the special characters depends on the word in question. It is important to understand that the actual rendering of these characters depend upon the context.
People are truly living untethered \u00e3\u0192\u00e6\u2019\u00e3\u201a\u00e2\u00a2\u00e3\u0192\u00e2\u00a2\u00e3\u00a2\u00e2\u201a\u00ac\u00e5\u00a1\u00e3\u201a\u00e2\u00ac\u00e3\u0192\u00e2\u00af\u00e3\u00a2\u00e2\u201a\u00ac\u00e2 \u00e3\u201a\u00ef\u2020, by buying and renting movies online, downloading software, and sharing and storing files on the web. Another common issue to consider is the impact of character encoding issues on database operations. I ran an SQL command in phpMyAdmin to display the character sets, a step that allowed me to analyze the encoding settings of my database tables. The main point of this command is to show the character encoding used by my database.
When you encounter these problems, it's easy to fix these issues by correcting the character set within the affected table. I am using SQL Server 2017, and the collation is set to sql_latin1_general_cp1_ci_as. Similarly, for other database systems, there are equivalent settings you can adjust. This is critical for preventing the mojibake problem in future data inputs.
For example, the character "\u00c3" represents the "Latin capital letter a with circumflex."
Harassment is any behavior intended to disturb or upset a person or group of people. Threats include any threat of violence, or harm to another. Addressing these issues require an understanding of how character encodings function and how to fix the problems that arise from their misuse.
Tools like "ftfy" ("fixes text for you") can be very useful for automatically correcting common text errors, including mojibake. It is useful because it takes the burden of manually translating each character. Also, it provides a set of ready SQL queries which can be used in SQL Server as well as other databases. This makes the data clean in no time.
If the file opens correctly in a text editor, but looks corrupted elsewhere, it is very likely your application or software is the culprit. When a page is designed in UTF-8 and then the user tries to enter special characters such as accents, question marks, and tildes in Javascript, they will come up with the problems that we're dealing with. When you have to deal with strange characters in your databases, and on web pages, you should consider that the text files have been corrupted.
When your data exhibits this corruption, it's a clear sign of a character encoding mismatch. For instance, instead of an expected character, a sequence of latin characters is shown, typically starting with \u00e3 or \u00e2. It is the Latin capital letter a with circumflex.
