Bug #65400 for Text-Markdown: Multimarkdown features

Terr! I try to implement Multimarkdown to my webapp and don't have full picture, which features are supported in Perl module? For example, i'd like to have support for MathML and pretty punctuation, but seems to me, that MultiMarkdown in perl package does not have them supported. I use module as deb-package under Debian, here are Markdown and MultiMarkdown together in single package, version 1.0.21-1. For example input: << e^(i pi) + 1 = 0 [Euler's identity]>> Should have such output (i got it with Fletcher's MultiMarkdown.pl tool): <p><math xmlns="http://www.w3.org/1998/Math/MathML" id="eulersidentity" display="block"><mstyle><msup><mi>e</mi><mrow><mi>i</mi><mi>&#x03C0;</mi></mrow></msup><mo>+</mo><mn>1</mn><mo>=</mo><mn>0</mn></mstyle></math></p> With perl module i got just: <p>&lt;&lt; e^(i pi) + 1 = 0 [Euler's identity]>></p> Also i'd like to use Pretty Pants extension, but it did not work either, for input: Where are my "pretty" quotes I got output: <p>Where are my "pretty" quotes</p> Instead i wanted <p>Where are my &#8220;pretty&#8221 quotes</p> Same time, for example, tables work fine. So, should those extensions work with Perl module and/or what should i do to get them work. Thank you in advance! -- Wbr, Kõike hääd, Gunnar
