User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:19.0) Gecko/20100101 Firefox/19.0 Build ID: 20130307023931 Steps to reproduce: Go to Settings -> Language -> Change from English (US) to Arabic in the languages list Actual results: After the language is changed, the entry for 'English (US)' becomes '(English (US' - parentheses are displayed wrong, which occurs for any language that has details in parenthesis (e.g. Brazilian Portuguese, Simplified Chinese, etc) Expected results: The label for languages that contain details in parenthesis should remain unchanged -- i.e. parentheses should not be misplaced

This bug shows the same behavior as Bug 847739, whose proposed solution is to add a Unicode control character after the right-hand side parenthesis so that the algorithm behind bidirectional script support does not interpret the parentheses wrong in RTL languages (e.g. Arabic) -- see http://www.w3.org/International/tutorials/bidi-xhtml/#again for example of this behavior.

We're not shipping Arabic (or RTL languages) in v1 so not tracking.

This bug is a follow-up of Bug 847739, highlighting the same behavior for language selection as for FTE, but in the settings app. Lukas, Bug 847739 got tracking-b2g18:+ and was merged to gaia/master, shouldn't this bug also get the flag? Conceptually it tackles the same behavior but in a different app.

Delphine, you confirmed Bug 847739, can you also confirm this one? Thanks!

Since markup is not allowed inside 'option' tags, the strongly-typed Unicode control characters Left-to-Right Embedding (LRE - U+202A), Right-to-Left Embedding (RLE - U+202B) and Pop Directional Formatting (PDF - U+202C) where used to wrap the language labels.
