Problem

When using RTL languages (e.g., Arabic), parentheses in language display names appear incorrectly due to a known Flutter SDK bidirectional text rendering issue.

Related Flutter issues:

• flutter/flutter#122500
• flutter/flutter#108431

Solution

Update language display names to use a dash instead of parentheses:

• English (United States) → English - United States
• Español (España) → Español - España
• Español (Argentina) → Español - Argentina
• Français (France) → Français - France
• Français (Canada) → Français - Canada

This workaround avoids the Flutter bidi algorithm issue with parentheses.

Line: 1.x / JNAP

Root cause:

• UI defect: Flutter SDK bidirectional text algorithm mishandles parentheses in language display names when UI locale is RTL (e.g. Arabic), causing incorrect character ordering. This is a known Flutter SDK issue (flutter/flutter#122500, flutter/flutter#108431) with no SDK-level fix available. Workaround: replace parentheses with - in the 5 affected locale strings.

Evidence (from issue body):

Affected display name strings:

English (United States) → English - United States
Español (España)        → Español - España
Español (Argentina)     → Español - Argentina
Français (France)       → Français - France
Français (Canada)       → Français - Canada

Related Flutter upstream issues confirming SDK-level bidi bug with parentheses:

• flutter/flutter#122500
• flutter/flutter#108431

Confidence: Medium — root cause confirmed via Flutter upstream issues; no attached screenshot/log to verify runtime rendering on device, pending visual verification.
