Line 2,005:
In Lua, a character is always the size of one byte so there is no difference between byte length and character length.
===Byte Length===
Byte length in UTF-8:
<syntaxhighlight lang="lua">str = "Hello world"
length = #str</syntaxhighlight>
Line 2,015 ⟶ 2,019:
===Character Length===
Only valid for ASCII:
<syntaxhighlight lang="lua">str = "Hello world"
length = #str</syntaxhighlight>
Line 2,022 ⟶ 2,029:
<syntaxhighlight lang="lua">str = "Hello world"
length = string.len(str)</syntaxhighlight>
For Unicode string, use utf8 module:
<syntaxhighlight lang="lua">
utf8.len("møøse")
utf8.len("𝔘𝔫𝔦𝔠𝔬𝔡𝔢")
utf8.len("J̲o̲s̲é̲")
</syntaxhighlight>
