I'm trying to typeset a word that contains a 'Č', and due to context, it has to appear in a sans, bold, quattrocento font.

However, whenever I have the fontencoding set to T1, then the character doesn't appear at all. The following MWE creates a blank page but should create a single bold sans 'Č'.

Commenting out the fontenc line seems to fix the problem, but I'd prefer to have a special case for this character then change the fontencoding for the entire document

MWE:

usepackage[T1]fontenc

usepackage[sf,scaled=0.9]quattrocento

begindocument
textbftextsfvC
enddocument

The font misses several precomposed accented glyphs. At the expense of the possibility to hyphenate the words containing Č, you can do

documentclassarticle
usepackage[T1]fontenc
usepackage[sf,scaled=0.9]quattrocento

providecommand*UndeclareTextComposite[3]%
 expandafterletcsnameexpandafterstringcsname
 #2endcsnamestring#1-#3endcsnamerelax

UndeclareTextCompositevT1C

begindocument

textsfvC
textbftextsfvC

enddocument

See https://tex.stackexchange.com/a/58115/4427 for UndeclareTextCompositeCommand. Do similarly for other missing accented characters you need.

It's immaterial whether you use vC or directly Č.

Note. The maintainer of the LaTeX font package remarked that the glyphs are missing because they're not even in the OpenType font the TeX version is derived from.

Here is another solution using the OpenType font. The version of Quattrocento Sans I downloaded does not contain the Unicode characters U+030C (combining caron) or U+010C (Latin Capital Letter C with Caron), but you can fake it with U+02C7 (Caron) and accent. You can also use Ulrike Fischer’s solution to this similar problem.

documentclassarticle
usepackagefontspec, newunicodechar

defaultfontfeaturesScale = MatchLowercase
setmainfontQuattrocento Roman[Scale = 1.0]
setsansfontQuattrocento Sans

renewcommandv[1]accent"02C7 #1
newunicodecharČvC
newunicodecharčvc

begindocument
textbftextsfvCČ
enddocument

Warning: this supports Č (U+010C), but won’t necessarily work if you write it as Č (U+43 U+030C).
