Logging on Windows command prompt can be garbled

[abelcheung]

Currently glib logging doesn't use Windows console API, unlike stdout / stderr counterparts. Sometimes it can contain garbled characters (like ideographic quotes).

• Possibly need a replacement of g_log_default_handler()
• stdout handle needs to be initiated early too, for help message printing.

Delayed milestone for this issue. Replacing g_log_default_handler() requires copying large chunk of glib code that recurses deep down, and seems to require glib internal funcs too. Not an easy replacement, and probably unworthy, as log messages are already in English and unlocalised now. Current problem mainly happens in unicode quotes.

Tremendous effort but little gain. Closing.
