Template:Mbox The Template:Chr extracts a specified nth character from a string, even allowing for accented letters to be included in the string.
Usage
- {{Chr|text|n}} = Returns the n-th character of text.
Supports a larger character set, allowing the text to have accented letters. Returns an error message for unknown characters.
Examples
- {{ Chr |0123456789ABCDEF|15}} → E
- {{ Chr |ÁBĆĎÉf-ABCDEF|4}} → Ď
- {{ Str len |{{ Chr |a b|1}}}} → 1
- {{ Str len |{{ Chr |a b|2}}}} → 0
- {{ Str len |{{ Chr |a b|3}}}} → 1
The last example shows extraction of letter "b" with string length as 1. The prior example extracts a blank but considers the length as 0, for there are no characters. If surrounded by 2 other characters, then the length would be totalled as 3 characters:
- {{ Str len |<{{ Chr |a b|2}}>}} → 3
- {{ Str len |X{{ Chr |a b|2}}X}} → 3
- {{ Str len |X{{ Str index any |a b|2}}X}} → 25
- X{{ Chr |a b|2}}X → X X
A string-length problem occurs when using template {{ Str index any }}.
