Hi,

In this particular case, it >translates `|' to `\(bv'. `bv' is equivalent to `braceex' in PS Hm, here's a suse'd perlcheat.1.gz, which when viewed with a plain text editor, contains $|, and not \(bv. (http://jengelh.hopto.org/f/perlcheat.1.gz) In the "devutf8/R" file is: ba 24 0 0x007C or " | " rC 24 0 0x007D ... br 24 0 0x2502 bv " rk 24 0 0x251D >Regarding the grave accent mapped to U+0x2018, here is the comment >from groff_char(7): > > ` the ISO Latin-1 `Grave Accent' (code 96) prints as <U+2018>, > a left single quotation mark; the original character can be > obtained with `\`'.

For example, in my SuSE 9.1, I have >this in /usr/share/groff/site-tmac/tmac.andocdb: > > .if '\*[.T]'utf8' \{\ > . char \- \N'45' > . char - \N'45' > . char ' \N'39' > .\} Yes the andocdb is a hack, really. But adding all hacks, including the | mentioned above, would be an overkill. >To summarize: > > . Mapping `|' to the `bv' entity is strange. If you use a plain `|' > in a troff input file, you actually get a plain `|'! This looks > like a bug in Pod::Man. See my posted perlcheat.1.gz (a SUSE 9.2 "original ;). It has a plain |, but still gets a vertical bar. >PS: Why the heck is `perlcheat.man' and all other non-program man > pages of perl in man section 1? All manpages of "core perl" are in section 1. All *Perl module* manpages are in section 3pm. Well, I do not know why they are, I guess because they don't fit in any other category- 2-syscalls and stuff 3-libc functions 4-block and char devices 5-config files 6-games 7-protocols 8-sysadmin 9-kernel Jan Engelhardt -- _______________________________________________ Groff mailing list Groff@gnu.org http://lists.gnu.org/mailman/listinfo/groff
