If accented letters display incorrectly, your files and website settings may use different character encodings.
Apache can set a default encoding for HTML and plain-text responses. For files saved as UTF-8, use this line in your .htaccess file:
AddDefaultCharset utf-8
Use AddDefaultCharset Off to disable this default. The setting also applies to subdirectories unless overridden.
This directive does not convert files. Select the encoding in which your content is actually saved. See the Apache documentation for details.
