 Simply create a variable with the *plural* name of the taxonomy

-**taxonomy values are case insensitive**
+## Preserving taxonomy values
+
+By default, taxonomy names are hyphenated, lower-cased and normalized, and then
+fixed and titleized on the archive page.
+
+However, if you want to have a taxonomy value with special characters
+such as `Gérard Depardieu` instead of `Gerard Depardieu`,
+you need to set the `preserveTaxonomyNames` [site configuration](/overview/configuration/) variable to `true`.
+Hugo will then preserve special characters in taxonomy values
+but will still titleize the values for titles and normalize them in URLs.
+
+Note that if you use `preserveTaxonomyNames` and intend to manually construct URLs to the archive pages,
+you will need to pass the taxonomy values through the `urlize` template function.
