Pango 1.17及更新版本支持使用'''locl'''标签允许同一Unicode码点的本地化字符的使用。<!--Assuming you have [[Verdana]] version 5.01 installed, which supports the locl feature for the latn/ROM (Romanian) script, a quick demonstration (on Linux) is:
<source lang="bash">
for lang in en ro; do pango-view \
 --font="Verdana 64" \
 --text "şţ vs. șț in $lang" \
 --language=$lang; done
</source>

For an explanation of the substitutions rules for Romanian, see this [[Romanian alphabet#Comma-below .28.C8.99 and .C8.9B.29 versus cedilla .28.C5.9F and .C5.A3.29|discussion]].

Setting the locale via the POSIX environment variable, e.g. LANG=ro_RO.UTF-8 will also cause Pango to use '''locl''' font feature. Finally, you can change the language on the fly in the same text using [http://library.gnome.org/devel/pango/unstable/PangoMarkupFormat.html Pango markup], e.g.:

<source lang="bash">
pango-view \
 --font="Verdana 24" \
 --markup \
 --text 'In the same text: <span lang="en">şţ</span>(en) and <span lang="ro">şţ</span>(ro).'
</source>

The official showcase of Pango's script-aware features is [http://www.pango.org/ScriptGallery here].-->

从1.37.1版开始，Pango添加了更多属性来提供处理OpenType功能的完整支持。<ref>{{cite web
