LightWave Client: Diagnostic log may be corrupted when the request or response HTTP body contains multi-byte characters.


When LightWave Client writes the diagnostic log, the log content is wrapped at character position 130. If the request or response HTTP body contains multi-byte characters, and the length of a line exceeds 130 characters, the line wrapping algorithm may split the line within a multi-byte character, corrupting the log. While the log may be viewed as an enscribe file with the corrupted characters, it will not load into the console Diagnostic Log view.
