Russian alpha index

How to add support of russian language to alpha index of flexicontent?

Hi,
This is a good question
What happens if you edit components/com_flexicontent/templates/default(or your template)/category_alpha.php
and replace line 25 by your alphabet?
I've no experience with that but it may probably function.
Cheers,
Emmanuel.

In category_alpha.php

i has replaced strtoupper($letter) to
mb_strtoupper($letter), because strtoupper() doesn't support russian UTF8 encoding.

in category.php i changed the line to mb
$alpha[] = mb_strtolower(substr($title, 0, 1));

letters array looks like this:
$letters = array('a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z', 'а', 'б', 'в', 'г', 'д', 'е', 'ж', 'з', 'и', 'к', 'л', 'м', 'н', 'о', 'п', 'р', 'с', 'т', 'у', 'ф');

Changed letters array displayed correctly, however works only english index.

It seems russian symbols parsed incorrectly ( with enabled print_r($alpha) in code) it looks:

Array
(
[0] => �
[1] => t
[2] => b
)

[0] - its a russian symbol


Can you provide list of files where stored alphaindex functions? I try to fix this issue with yours help.

Thank You!

Hi,
The alpha index is processed as the filters. That means you can find it in the _buildItemWhere() method in the category model.
To link only the letters that have articles in, I use then the getAlphaindex() method
Any suggestion to improve that and make utf8 compliant is welcome.
Cheers,
Emmanuel.

Found some info about handling UTF-8 encoding:

substr
Impact: accepts arguments in bytes positions not characters - could corrupt a UTF-8 string

If used in an arbitrary manner to chop off part of a string, it could potentially split UTF-8 sequences resulting in corruption. At the same time if used in conjunction with functions like strpos (see notes above), would be able to extract a portion of a UTF-8 string without corrupting it, although you’ll be passing it arguments in terms of byte positions not character positions.

I added to all alphaindex functions mb_ prefix

$alpha[] = mb_strtolower(mb_substr($title, 0, 1));

symbols displays correctly, but sorting and indexing do not works ((

may be javascript function getElementById incorrectly parse ?
