Line 946: Nim has a <code>char</code> type whose values are contained in a single bit. The values from 0 to 127 are the ASCII characters. Strings are composed of char values but they are considered to be encoded in UTF-8. So accessing an individual character of a string may have no meaning when not working in ASCII. ~~The following program displays the lowercase and uppercase letters.~~ Note that Nim allows to work with full Unicode, either by using strings encoded in UTF-8 (but with limited possibilities) or by using the runes of the module “unicode”. Identifiers may contain Unicode letters or digits as in “θ₁”, “â”, “x₁”, “x³”. The following program displays the lowercase and uppercase ASCII letters. <syntaxhighlight lang="nim">import sequtils, strutils
