Chars missing after saving info in text area in IE

SA-15246

Summary



Line break takes one character on enter, but when saved, takes two characters, and if the field is full, then unexpected truncation occurs at the end. This behavior occurs in IE11.


Error Messages



Not Applicable


Steps to Reproduce



1. consider a TextArea control on a property of String type with max characters limit.
2. Enter symbols to fulfil max limit including one line break.
3. After saving the page – line break consumes two symbols, and text is cut.

 

Root Cause



A third-party product issue.

Resolution



Browsers may interpret the Carriage Return as multiple characters. The convention may be between '/n' and '/r/n'. In this case, the new line function is interpreted by IE as '/r/n.' This is counted by the browser as two characters as some database technologies will also use /r/n to create a new line, and they opt to make sure max character limits are obliged.

The behavior of counting the size of the new line as two bytes (\r\n) is expected and not a bug in the product.
