fix(windows): preserve localized profile paths - #1678

✅ Deterministic PR hygiene checks passed. |
📝 WalkthroughWalkthroughWindows PowerShell identity output now uses strict UTF-16LE Base64 decoding. A shared locale-aware Windows text decoder handles service-manager output, including Korean CP949 data. Windows probes pass the locale through all relevant decoding paths, with regression coverage for identity and service ownership paths. ChangesWindows identity output

Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to If locale detection fails, localized Windows output may be decoded with Windows-1252 and silently corrupt profile paths. The risk is bounded and the PR remains mergeable with explicit owner awareness or follow-up to skip legacy decoding when no locale is available. Possibly related PRs

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Do not select Windows-1252 when locale detection fails.
If Intl.DateTimeFormat() throws, currentWindowsLocale() returns "en-US". legacyEncodingForLocale("en-US") then selects "windows-1252". Windows-1252 accepts arbitrary byte values, so CP949 or unsupported-codepage output can be silently corrupted instead of retaining the replacement-preserving UTF-8 fallback described in src/lib/windows-text.ts.
Return null from the failure path. Skip legacy decoding when no locale is available.
Proposed fix
-function currentWindowsLocale(): string {
+function currentWindowsLocale(): string | null {
try {
return Intl.DateTimeFormat().resolvedOptions().locale;
} catch {
- return "en-US";
+ return null;
}
}
...
const locale = options.locale ?? currentWindowsLocale();
- const legacyEncoding = legacyEncodingForLocale(locale);
+ const legacyEncoding = locale === null ? null : legacyEncodingForLocale(locale);📝 Committable suggestion

[Repository bug audit · 2026-08-14]
The locale-safe decoding design is good: deterministic PowerShell Base64/UTF-16 output avoids console-codepage ambiguity, and the bounded CP949/Windows-1252 fallback is preferable to replacement-character guessing.
Blocking integration issue: this head still builds the direct identity command with -WindowStyle Hidden, while #1674 removes that exact argv pair because it fails under the affected Bun/Windows path. Merge #1674 first, then rebase this branch and preserve the Base64/UTF-16 command without reintroducing -WindowStyle Hidden.
After the rebase, rerun the Korean-profile-path/service-manager tests and an exact Windows smoke covering ocx sync, scheduled-task ownership, and LocalAppData identity resolution.
