[PATCH 1/2] t4205 (log-pretty-formats): Add failing tests for the case when i18n.logOutputEncoding is set

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Pretty format string %<(N,[ml]trunc)>%s truncates subject to a given
length with an appropriate padding. This works for non-ASCII texts when
i18n.logOutputEncoding is UTF-8 only (independently of a printed commit
message encoding) but does not work when i18n.logOutputEncoding is NOT
UTF-8.

There were no breakages as far as were no tests for the case
when both a commit message and logOutputEncoding are not UTF-8.

Add failing tests for that which will be fixed in the next patch.
