Clipboard

ClipReplace prioritizes safe text handling when it reads data from the clipboard.

Supported formats

Type	Support	Behavior
Plain string	Supported	Read first. If UTF-8 data is available, it is decoded strictly.
UTF-8 text data	Supported	Decoded strictly as UTF-8 before replacement.
HTML	Supported	Only plain-text extraction is used.
RTF	Supported	Only plain-text extraction is used.
Images / binary	Not supported	Fails if no usable text is available.

In mixed clipboard payloads such as image + HTML + RTF + text, ClipReplace processes only the highest-priority text representation.
Corrupted UTF-8 data or text that looks like binary data is rejected. HTML and RTF are converted to plain text before replacement; formatting is not preserved.

1,048,576 bytes

Output text limit

If the replaced result exceeds 1 MB, ClipReplace returns clipboardOutputTooLarge and does not write the result back.

HTML / RTF parsing limit

4,194,304 bytes

Rich-text to plain-text extraction is limited to 4 MB.
