Prestashop: LC_CTYPE & Turkish Language

[metineren]

Describe the bug
If setlocale is set to LC_CTYPE variable tr_TR, some of the Turkish characters are different from the en_US definition of PHP's strtolower or strtoupper method.

This character change affects the autoloader configuration of some vendor packages. Smarty for example.

This definition causes Smarty-like Vendor packages to fail to find the classes the autoloaders want to load.

en_US -> Smarty_Internal_Undefined -> smarty_internal_undefined.php
tr_TR -> Smarty_Internal_Undefined -> smarty_ınternal_undefined.php

To Reproduce
Steps to reproduce the behavior:
We need to change the locale in Debian with tr_TR.UTF-8 to reproduce the issue (tuto followed)

1. Try a new PrestaShop installation in Turkish language OR Try to Product Import/Export in Turkish Language
2. See error

Additional information
PrestaShop version: 1.7.6.2
PHP version: 7.2.x

Hi @metineren,

Thanks for your report.
What the exact error after importing/exporting the Turkish language.
It is ok in my case.

The classic theme exported in Turkish

Thanks to check & feedback.

Hi @khouloudbelguith ,

Your server configuration may prevent php from changing the LC_CTYPE parameter in the setlocale function.

can you try this code;
<?php $current_ctype = setlocale(LC_CTYPE, 0); setlocale(LC_CTYPE, "tr_TR.UTF-8", "tr_TR.utf8"); $changed_ctype = setlocale(LC_CTYPE, 0); echo $current_ctype.PHP_EOL; /* Return C */ echo $changed_ctype.PHP_EOL; /* Return tr_TR.UTF-8 */ ?>

@metineren,

I have this result

C
C

Thanks!

Then the server's LC_CTYPE parameter prevents you from entering it. In general, changing this parameter is not prohibited on servers.

If your server allowed to modify LC_CTYPE, you would be able to see the error I mentioned.

@metineren, I tried to change my configuration

But it seems ok when Importing the Turkish language.

Thanks!

Hi @khouloudbelguith ,
Can you retest the code I sent in the previous message?

[khouloudbelguith]

@metineren, it is the same

Thanks!

@khouloudbelguith ,
Looks like your change didn't really apply.

The Turkish language case conversion is different from the English language.
EG: Lowercase to Uppercase: i > İ, ı > I
EG: Uppercase to Lowercase I > ı, İ > i

LC_CTYPE for character classification and conversion, for example strtoupper()

You can see: https://www.php.net/manual/en/function.setlocale.php

Smarty' s autoloader search class name to lowercase if you can set tr_TR to LC_CTYPE in setlocale
The result:
tr_TR -> Smarty_Internal_Undefined -> smarty_ınternal_undefined.php

Or setlocale LC_CTYPE en_us The result:
en_US -> Smarty_Internal_Undefined -> smarty_internal_undefined.php

And notice: I' am from Turkey and my native language Turkish :)

If you need a server with an unrestricted LC_CTYPE definition to test, I can help if you send a private message.

@metineren, I manage to reproduce the issue with PS1.7.6.2 & PS1.7.5.2.
https://drive.google.com/file/d/1ZDVCjZPQArVqofjSIoFLiQRSPg13yRY5/view
I used my local, it is well configured.
Thanks a lot for your help!

This is better solved upstream -- see https://github.com/smarty-php/smarty/issues/155 for the equivalent issue in Smarty.
