Limits on Fonts Used in Arabic Windows 3.1 Edit Control

SUMMARY

In Arabic Windows 3.1, simple string functions are used to create, shape, layout, and output simple string objects. The string objects internally handle information about layout, bounding regions for visually discontinuous selected text, and glyph mapping (shaping). Edit control in Arabic Windows uses these simple string functions to manage its text.

However, simple string functions only work with ANSI and Arabic character set fonts. They do not work with italic fonts, OEM fonts, or SYMBOL fonts. If SYMBOL, OEM, or other non-ANSI, non-Arabic font is set for the edit control, the characters being typed into the edit control will not be displayed, although the characters are still being stored in the edit control, and can be retrieved using GetWindowText().
