-----------------------------------------

Hi Florian,

It will work most of the time, but not if the user has set LC_ALL or LANG in 
\*nix, or sets similar in Windows: 
https://stackoverflow.com/questions/10707238/locale-getdefault-returns-en-always

As I said we should use locale.ROOT, but, like you, I don't see how to set that 
in a template around the concerned line. So indeed RAINBOWSTONE_SPAHIR.less 
seems the safer and easier solution to me.

I'll maybe have a look at a Freemarker solution, thanks for your work.

> h3. If
>  * current locale is tr-TR (and most certainly az-AZ, maybe others, where 
> [dotless i|https://en.wikipedia.org/wiki/Dotless_I] exists),
>  * the theme name contains a "i" (`RAINBOWSTONE-SAPHIR` for example),
>  * the theme uses this line in /template/includes/Header.ftl to generate a 
> link to a Less file (rainbowstone, helveticus, maybe others) :
> {code:java}
> <link rel="stylesheet/less" 
> href="<@ofbizContentUrl>/helveticus/${visualTheme.visualThemeId?replace("_","-")?lower_case}.less</@ofbizContentUrl>"
>  type="text/css"/>{code}
> h3. Then
>  * the Freemarker `lower_case` function generates dotless i's when 
> lowercasing "I",
>  * the link to the Less ends up with a 404
>  * no more styles :/
> See [^turkish-dotless-i-bug.mp4]
> h3. Leads to fix this
>  * Find a way to override the current locale for `lower_case` calls (and 
> always use en-EN)
>  * Do not rely on a locale sensitive function to generate links to style files
>  * Ban "i" from visual theme names :)
>  * more ideas ?
