[PATCH v6 0/2] MR4812: user32: Fix the number of characters processed by DrawTextExW.
Description: When flags does not include DT_CALCRECT, since len is calculated in the middle, it will be reduced to zero. Resulting in the length of the processed string that is finally returned to zero and the non-processing string length is unchanged. But some application taking the non-processing string length to zero as the loop end condition.

Hi, It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated. The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful.
