 The following assertions compare two **C strings**. To compare two `string`
 objects, use [`EXPECT_EQ`](#EXPECT_EQ) or [`EXPECT_NE`](#EXPECT_NE) instead.
 
-These assertions also accept wide C strings (`wchar_t*`). If a comparison of two
-wide strings fails, their values will be printed as UTF-8 narrow strings.
+EXPECT_STREQ and EXPECT_STRNE also accept wide C strings (wchar_t*).
+Case-insensitive variants (EXPECT_STRCASEEQ and EXPECT_STRCASENE) currently
+do not support wide C strings. If a comparison of two wide strings fails,
+their values will be printed as UTF-8 narrow strings.
 
 To compare a C string with `NULL`, use `EXPECT_EQ(`*`c_string`*`, nullptr)` or
 `EXPECT_NE(`*`c_string`*`, nullptr)`.
