Bug #: 47750
Summary: Need to audit for [A-Z] regexp usage (might break
build with certain locales) in build scripts
Classification: Unclassified
Product: LibreOffice
Version: LibO Master
Platform: Other
OS/Version: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Libreoffice
AssignedTo: [email protected]
ReportedBy: [email protected]
This might sound a bit 'crackpot', but using [A-Z] range in build scripts can
introduce subtle issues under certain locales (one example is et_EE/Estonian)
because the A-Z range cuts off some regular ascii characters (tuvxy in
Estonian). This causes either build errors with package or even subtler issues
like some symbols in shared library don't exported...
The solution is to either prefix the commands where such kind of range is used
(sed, tr) with `LC_ALL=C` or writing out the whole ascii alphabet range
(abcd...xyz). Please note that '[:alpha:]' is not an answer and can cause
similar issues.
Some examples of the [A-Z] gone wrong:

Should note here that [:alpha:] was later replaced with full-range abcd..xyz:
