Many thanks. I find the following in the present
version in TeX Live 2018 (w32):

CLISP version 2.49.92 (2018-02-18)

#define VALID_FILENAME_CHAR ((ch >= 32) && (ch <= 61) && \
(ch != 34) && (ch != 42) && (ch != 47) && (ch != 58) && \
(ch != 60)) || ((ch >= 64) && (ch <= 132) && (ch != 92) && \
(ch != 124) && (ch != 130)) || ((ch >= 137) && (ch <= 234) && \
(ch != 152)) || ((ch >= 240) && (ch != 252))

Thanks,
Akira
