I found a strange encoding issue for text displayed during installation in the text console. WeiDU appears to switch character encoding from OEM 850 to Windows-1252.
A test mod to demonstrate:
TestEncoding.zip (

The test mod includes a single traified line that contains the special character 'Æ' in both OEM 850 and Windows-1252 encoding.
Text in component name is initially displayed in OEM 850 (expected), but subsequent copies of the same line are displayed in Windows-1252 encoding if you install the component (unexpected). Encoding stays in OEM 850 if you choose not to install the component.
(Tested on Windows 7 with western regional settings.)
