Being character arrays by definition, strings can also be used as ranges just by importing std.array. However, char and wchar strings cannot be used as RandomAccessRange.

std.array provides a special functionality with all types of strings. Iterating over strings becomes iterating over Unicode code points, not over UTF code units. As a result, strings appear as ranges of Unicode characters.

The following strings contain ç and é, which cannot be represented by a single char, and 𝔸 (mathematical double-struck capital A), which cannot be represented by a single wchar:
