ClipConvert is a utility to fix a problem that Windows 95 and 98, and in some cases NT, have when copying/pasting text in a codepage different from the system codepage. Something you run across often when doing localization tasks. In addition, it's also a good tool to examine the content of the Clipboard.

Environment: Windows 9x and NT 4.x

ClipConvert Purpose

Windows applications uses different formats to communicate with the Clipboard. When the text copied is not in the same codepage as the system codepage, this may cause lost of data.

For example:

If you copy let's say Russian text from Word. The Clipboard contains RTF and Unicode data as well as Plain text data. But because your system codepage is not 1251 (Cyrillic) the Plain text data are converted into question marks. An application like Notepad does not use RTF or Unicode but Plain text and will paste question marks instead of the Russian text (even if you have Russian support installed and could type Russian text in Notepad).

To fix this, ClipConvert takes the Unicode text Word places in the Clipboard and converts it to its proper code set (that you can pick). When Notepad pastes the Plain text the Cyrillic characters are correct.


If you copy Russian text from Notepad. The Clipboard contains only Plain text data (in Cyrillic). When you paste it in Word (96 or later), because it expects the Plain text to be in the same codepage as the system codepage, the Cyrillic characters are lost and replaced by whatever extended character the system codepage has at the same code-points.

To fix this, ClipConvert takes the Plain text data and creates RTF and Unicode entries based on the codepage you pick. When Word paste the text, it can use the RTF or Unicode data rather than the Plain text, and pastes the proper Cyrillic characters.

You should close ClipConvert or disable the "Auto-convert" options when doing "normal" Copy/Paste commands. Use it only when exchange text in a non-system codepage between two applications not using the same Clipboard data. ClipConvert can also be useful to look at what an application places in the Clipboard.

The Implementation

When starting, ClipConvert inserts itself into the Clipboard chain and monitors any Copy command. If the "Auto-convert" option is set, it immediately converts the Clipboard contents according the rules described above. The next time an application executes a Paste command, it gets the converted data

To be more generic, ClipConvert uses its own code sets tables, allowing to convert more than just the Windows codepages. The package posted here includes conversion tables for all Windows codepages, including Thai, Arabic, Hebrew, Japanese, Chinese, etc. as well as for UTF-8 and UCS-2. Contact me if you need Macintosh or ISO tables.
