In a perfect world, the proper character set will be set at the server level.
Details here. It is advisable to back up the table first. Some discussion is in order. This has no effect on the internal data, but it affects the way you see the output. The encoding you want to use is not simply called utf8. MySQL uses a three-byte encoding scheme if you tell it to use utf8. What you really want instead is utf8mb4 , giving you full four-byte capabilities. Annotation of the code follows.
I found that this worked out well. You might want to install this script on your server and run it. You can adjust the character settings to see the different outcomes and symptoms of success or failure.
Most Microsoft "Office Productivity" applications make the assumption that your data is in ANSI format, generally rendering the data in CP or a similar character set, without regard to the fact that the data may be UTF-8 encoded. This comes into play if your scripts write CSV files that need to be opened in Excel.
Although the Excel software is almost universally associated with the. Since UTF-8 is self-evident, this ability should be built into Excel some day. And the good news is that it appears that the Microsoft applications preserve the data values, even though they garble the screen rendering I have only tested this Excel. If your web site is using the ISO character set, the special quotes and other quirky characters that Word creates will go through unalloyed. Fortunately there is an easy way around this issue, via a built-in PHP function.
These entities will be displayed correctly in any browser. Here is a sample script that shows how it works. You can install this on your server and run it to see the translation in action. It comes with a gentle warning, however. This means that you incur a risk of data truncation if your script translates the data before storing it in your data base.
Check your column widths carefully to avoid data loss. Consider the following code snippet, created using a Mac program called TextWrangler. It's not the quotation mark at decimal code point 34!
It looks a lot like a quotation mark, enough so that it's visually confusing. I need to encode the data using ISO for the destination system, but obviously using the data as-is yields the incorrect results in ISO the per mille sign is represented by decimal , as per this chart.
I need some advice on what encoding I can use when reading the data - i. I found my answer in this SO post. I was thus able to re-encode the data as follows:.
