The '''Template:str_index_any''' extracts a specified nth character from a string, even allowing for accented letters to be included in the string.

=== Usage ===
:: <nowiki>{{</nowiki>'''str index any'''|''text''|''n''<nowiki>}}</nowiki> = 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. Returns &amp;#32; for a blank space.

=== Examples ===
* {{tlp| {{BASEPAGENAME}} |0123456789ABCDEF|15}} → {{ {{BASEPAGENAME}} |0123456789ABCDEF|15}}
* {{tlp| {{BASEPAGENAME}} |ÁBĆĎÉf-ABCDEF|4}} → {{ {{BASEPAGENAME}} |ÁBĆĎÉf-ABCDEF|4}}
* <nowiki>{{</nowiki> Str len |{{ {{BASEPAGENAME}} |a b|1<nowiki>}}}}</nowiki> → {{ Str len |{{ {{BASEPAGENAME}} |a b|1}}}}
* <nowiki>{{</nowiki> Str len |{{ {{BASEPAGENAME}} |a b|2<nowiki>}}}}</nowiki> → {{ Str len |{{ {{BASEPAGENAME}} |a b|2}}}}
* <nowiki>{{</nowiki> Str len |{{ {{BASEPAGENAME}} |a b|3<nowiki>}}}}</nowiki> → {{ Str len |{{ {{BASEPAGENAME}} |a b|3}}}}

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 "&amp;#32;" even though there is only 1 space, and hence, <nowiki>{{str len|&amp;#32;}}</nowiki> &rarr; {{str len|&#32;}}. If surrounded by 2 other characters, then the length might be totalled incorrectly as 7 (rather than 3 characters):

* <nowiki>{{</nowiki> Str len |<{{ {{BASEPAGENAME}} |a b|2<nowiki>}}>}}</nowiki> → {{ Str len |<{{ {{BASEPAGENAME}} |a b|2}}>}}
* <nowiki>{{</nowiki> Str len |X{{ {{BASEPAGENAME}} |a b|2<nowiki>}}X}}</nowiki> → {{ Str len |X{{ {{BASEPAGENAME}} |a b|2}}X}}
* <nowiki>{{</nowiki> Str len |X{{ Str index |a b|2<nowiki>}}X}}</nowiki> → {{ Str len |X{{ Str index |a b|2}}X}}
* <nowiki>X{{</nowiki> {{BASEPAGENAME}} |a b|2<nowiki>}}X</nowiki> → X{{ {{BASEPAGENAME}} |a b|2}}X

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