Bug ID: 116872
Summary: gcc accepts unnormalized identifiers
Product: gcc
Version: 14.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: michael.kenzel at gmail dot com
Target Milestone: ---
According to [lex.name]/1, a program that contains an identifier that's not in
Unicode Normalization Form C is ill-formed.
gcc does not seem to correctly diagnose this issue.
For example, the following code is accepted without error or warning:
int \u00B5; // this should be ill-formed, MICRO SIGN cannot appear in
NFC
