I can't imagine naming variables using any other language but English. I spent some time as a consultant auditing other companies' software. Even with platforms where the coding-standards dictated the use of English, most of the projects I audited in Europe used the local language, rather than English - especially in variable names. Admittedly there was a selection bias - I wasn't ever hired to audit perfectly good software - but it was remarkably common.
