Cohabitation whole site iso-8859-1 with FluxBB 1.4 utf8

Hello,

I apologize for my wrong English.
My site (Sorry, only in French) (http://aviatechno.free.fr) has all pages with charset iso-8859-1.

Update from FluxBB 1.2.22 to FluxBB 1.4 (RC1 yet) poses two main problems :

- 1 - Transcoding the database from iso-8859-1 (latin1) to utf-8
With db_update.php and queries ALTER TABLE ... CONVERT TO CHARSET ... I think I have solved this problem. Moreover, db_update.php is improved each day...

- 2 - Having in the same site, pages in iso-8859-1 and others in utf-8
Indeed, all pages of my site (over 2,800) are iso-8859-1 as well as pages FluxBB 1.2.x forum that will have to be replaced by FluxBB 1.4 with utf-8 pages.
Integrating the forum into my site uses common files by include or require and it will be the same with FluxBB 1.4.
As it is totally out of question that I spend all my pages in utf-8, I discussed the issue of using files in either iso-8859-1 (baseline) or utf-8 and how to.
Integrating FluxBB 1.4 (It's the same with version 1.2.x) uses a file "FluxBB\include\user\menu_haut.php" called by main.tpl :

<pun_head>
</head>
<body>
<pun_include "menu_haut.php"> <!--modif oto ligne ajoutée -->
<div id="punwrap">
<div id="pun<pun_page>" class="pun">

As this file is only used by FluxBB, it may be hard coded in utf-8, but it uses six "cascaded" include files that are also used by a multitude of pages on my site and there is no question to move its in uft-8 or use utf-8 renamed copies because they can be updated frequently.
I searched for a permanent and automatic solution and I think I have found it.

In the file above integration (FluxBB\include\user\menu_haut.php), I defined a function named include_utf8:

// Change the charset of the file from iso-8859-1 to utf-8
// save the file recoded with added "utf8_" at the beginning of the name
// returns the changed file path. (In the directory cache of FluxBB)
// DOSSIER is the path to the root
function include_utf8($fichier) {
  $outfile = DOSSIER."fluxbb/cache/utf8_".basename($fichier);
  if (!file_exists($outfile))
    file_put_contents($outfile,iconv("ISO-8859-1","UTF-8",file_get_contents($fichier))); 
  return $outfile;
}
//First integration include
include(include_utf8('../vilgenis/inc/menu_h_vilgenis.php'));

The first file will be recoded utf8 before being included (But the original will not be changed or renamed).
In other files in "cascading include" (a includes b which includes c, which includes d...) just change the lines of the original inclusion as:

include('path_of_file');

by

if(function_exists('include_utf8')) include(include_utf8('path_of_file'));
else include('path_of_file');

Some might object that I could be include directly in the function include($outfile);
It is not possible, because it makes a big mess if the include occurs inside a function ; the code included will be considered part of the function and it loses the variable scope of that file that become local to function.
Results are here :

- Forum FluxBB 1.4 utf-8 : http://aviatechno.free.fr/fluxbb/

Hello,

Due to questions raised by users and some thoughts and attempts, I greatly simplified to cohabit a site iso-8859-1 with FluxBB utf-8

Instead of changing all include files in cascade, it can simply change the call by using memory buffer and then perform the transcoding before posting.

So, the file "fluxbb\include\user\menu_haut.php" called by main.tpl containing:

include ('../vilgenis/inc/menu_h_vilgenis.php ');

is remplaced by:

//Change the charset of all cascading includes from iso-8859-1 to utf-8
function convert_iso_utf($buffer) {
  return utf8_encode($buffer);
}
ob_start("convert_iso_utf");
include('../vilgenis/inc/menu_h_vilgenis.php');
ob_end_flush();

Conclusion: we do not modify the original files and any changes will be reflected without having to delete the cache files because no more cache files.
