This can result in the loss of data.
However this behavior can be disabled by Going to Properties -> Advanced -> FixCaseRenames and setting this to false. It appears that others have encountered this and posted to StackOverflow here: https://stackoverflow.com/questions/12763444/changing-filename-case-with-tortoisesvn-on-windows
Perhaps the folder should be queried to see if SetCaseSensitiveInfo and automagically disable this feature for those folders to avoid data loss in these scenarios?
At very least it might be worth updating the FAQ here https://tortoisesvn.net/faq.html#casechange
As an aside case sensitivity is one of the ones specifically called out by Raymond Chen's "The bug farm" https://devblogs.microsoft.com/oldnewthing/20110920-00/?p=9603 I can refrain from posting additional reports as our issue is resolved; Thank you for this great tool!
"A lot of testers suddenly realized that case sensitivity is a veritable bug farm on a project that thinks it is ready to go, but has not yet tried it."
