Template:Mbox The Template:str_index_any extracts a specified nth character from a string, even allowing for accented letters or diacritics to be included in the string. The string can be any length, but position n (parameter 2) is limited to 500 at most.

Usage

{{str index any|text|n}} = Returns the n-th character of text.

Supports a larger character set, allowing the text to have accented letters or other diacritical marks. Returns an error message for unknown characters. Returns &#32; for a blank space, which can be converted to a simple space by xspace.

Examples

The last example shows extraction of letter "b" with string length as 1. The prior example extracts a blank but considers the length as 5 for the 5 characters "&#32;" even though there is only 1 space, and hence, {{str len|&#32;}} → 5. If surrounded by 2 other characters, then the length might be totalled incorrectly as 7 (rather than 3 characters):

  • {{ Str len |<{{ Str index any |a b|2}}>}} → 25
  • {{ Str len |X{{ Str index any |a b|2}}X}} → 25
  • {{ Str len |X{{ Str index |a b|2}}X}} → 25
  • X{{ Str index any |a b|2}}X → XTemplate:Str ≥ lenX

The same string-length problem occurs when using template {{ Str index }}. There might be other quirks as well, but most cases work as expected.
