Symptoms
When you configure Windows Vista to use the High Contrast color scheme, some of the text in a Japanese program is not displayed in Japanese characters. Instead, this text may be displayed in English characters or in garbled or unrecognizable characters. When you restore Windows Vista to a default color scheme, the Japanese program displays text in Japanese characters as expected.
You experience this problem if you use the keyboard shortcut that enables the High Contrast color scheme. For example, you experience this problem if you press left SHIFT+left ALT+PRINT SCREEN to enable the High Contrast color scheme.
Cause
When you press left SHIFT+left ALT+PRINT SCREEN to enable the High Contrast color scheme, Windows Vista incorrectly changes the code page of the device context for the program. Specifically, Windows Vista changes the code page to 0x4e4 (1252 English) instead of to 0x3a4 (Japanese). Therefore, some double-byte characters may be rendered incorrectly.
Workaround
To work around this problem, use the Ease of Access Center tool to enable the High Contrast color scheme. To do this, follow these steps:
-
Click Start
-
Click Set up High Contrast, and then click the Choose a High Contrast color scheme link.
-
In the Color scheme list, click a color scheme, and then click OK.
Status
