Description

The localedef utility fails to generate multibyte characters whose initial prefix (leading byte) is the same as some single-byte character. The test case below demonstrates the problem:

$ cat charmap && cat ctype && ./localedef -c -w -f charmap -i ctype /tmp/dummy && LC_ALL=/tmp/dummy ./locale --charmap
CHARMAP
<U0041> \x41
<U0141> \x41\x42
<U0241> \x41\x43
END CHARMAP
LC_CTYPE
END LC_CTYPE
<escape_char> \
<comment_char> #
<code_set_name> charmap
<mb_cur_max> 1

1. charmap data:
2. charmap name = charmap
3. n_to_w_tab_off = 0
4. w_to_n_tab_off = 1024
5. utf8_to_ext_tab_off = 4096
6. xliteration_off = 7168
7. wchar_off = 8192
8. codeset_off = 8216
9. charmap_off = 8224
10. codecvt_ext_off = 0

CHARMAP
<U0041> \x41 # L'\x41'
END CHARMAP

1. charmap stats:
2. number of tables = 1
3. number of characters = 1
4. number of unused slots = 255 (100% waste)
