generate from dbc err

[aawuliliaa]

### first step:
i use Canmatrix convert arxml to dbc
canconvert ./Clea_Mode_Year23_VCU_V25.62.0.arxml ./ttest.dbc
ldf is not supported
INFO - convert - Importing ./Clea_Mode_Year23_VCU_V25.62.0.arxml ...
INFO - convert - done

INFO - convert - Exporting ./ttest.dbc ...
INFO - convert - ICB

WARNING - dbc - Signal Active_Safety_Customization_Info::ITrfcLgtStpLnCntrlCustCrntStngVal name exceeds 32 characters, consider updating the signal name within the character limit(Max 32 characters)

second step:

i run CGO_ENABLED=0 GOOS=darwin GOARCH=amd64 go build cmd/cantool/main.go to generate main

third: i use main to generate from dbc

./main generate /Users/wulili/Desktop/pythonProject/ /Users/wulili/Desktop/pythonProject/cango
main: error: failed to parse DBC source file: /Users/wulili/Desktop/pythonProject/ttest_ICB.dbc:6597:13: invalid identifier 'NWM-Knoten': invalid char: '45' (parse), try --help
can you tell me how to deal with this.
