\char"xxxx not working as I expected

\char"xxxx not working as I expected

[Maurí­cio]

Hi,

I'm trying this small test on unicode characters, and
the result I get is this:

http://173.45.227.76/test3.pdf

I did check the font in 'gucharmap' and it does contain
all codes I'm using (U+2019, U+2610, U+226b, U+2115). But
the result is a blank (U+2610 and U+2115) or wrong
(U+226b) character. (U+2019 is shown properly.)

The test alternates lines where a unicode character is
inserted directly (using emacs 'ucs' input method) and
then insert the same character using '\char'. (So, if you
see strange chars in the code, it's because it does
contain utf-8 characters.) It's intersting that u+226b
is shown properly when typed, but not when using '\char'.

Am I doing something wrong?

Thanks,
Maurício

A few unicode characters: ó ñ ï ỳ

(’) is character U+2019

(\char"2019 ) is also character U+2019

(☐) is character U+2610

(\char"2610 ) is also character U+2610

(≫) is character U+226b

(\char"226b ) is also character U+226b

(ℕ) is character U+2115

(\char"2115 ) is also character U+2115

1. You need a font with the chars, e.g. Arial Unicode
2. Use uppercase letters for hex numbers (lowercase is used for ^^..)

I have no idea what gucharmap is, but the font *does not*
have U+2115, nor U+2610. I verified that in fontforge.

> (U+226b) character.

The "b" should be a "B". TeX-style hexadecimal
values are always uppercase (\char"226B works for me).

Best wishes,
Taco

gucharmap will fallback to another font if the selected font don't
have the required character, so this doesn't necessarily mean the font
has those characters.
