 Note that the ASCII one-byte character codes (hexadecimal `00`-`7F`) are a subset of UTF-8.
 
 Before version 1.12, CF did not require text in **`char`** arrays to be encoded with UTF-8, and did not provide or endorse any convention to record what encoding was used.
-If the array is stored in a variable, the encoding might be recorded by the **`_Encoding`** attribute, which is not a CF or NUG convention.
+If the array is stored in a variable, the encoding might be recorded by the **`_Encoding`** attribute, although this is not a CF or NUG convention.
 If the data-user has no information about the encoding, we suggest UTF-8 as a first guess.
 
-An __n__-dimensional array of strings may be implemented as a variable or an attribute of type **`string`** with _n_ dimensions (only one dimension is allowed for an attribute) or as a variable (but not an attribute) of type **`char`** with _n_+1 dimensions, where the most rapidly varying dimension (the last dimension in CDL order) is large enough to contain the longest string in the variable.
-For example, a **`char`** array containing the names of the months would be dimensioned (12,9) in order to accommodate "September", the month with the longest name.

+For example, a **`char`** variable containing the names of the months would be dimensioned (12,9) in order to accommodate "September", the month with the longest name.
 The other strings, such as "May", would be padded with trailing NULL or space characters so that every array element is filled.
-A **`string`** array to store the same information would be dimensioned (12), with each element of the variable containing a string of the appropriate length.
+A **`string`** variable to store the same information would be dimensioned (12), with each element of the array containing a string of the appropriate length.
 The CDL example below shows one variable of each type.
