C# How to replace Microsoft's Smart Quotes with straight quotation marks?

Question

My post below asked what the curly quotation marks were and why my app wouldn\'t work with them, my question now is how can I replace them when my program comes across them,

To extend on Nick van Esch's popular answer, here is the code with the names of the characters in the comments.

if (buffer.IndexOf('\u2013') > -1) buffer = buffer.Replace('\u2013', '-'); // en dash
if (buffer.IndexOf('\u2014') > -1) buffer = buffer.Replace('\u2014', '-'); // em dash
if (buffer.IndexOf('\u2015') > -1) buffer = buffer.Replace('\u2015', '-'); // horizontal bar
if (buffer.IndexOf('\u2017') > -1) buffer = buffer.Replace('\u2017', '_'); // double low line
if (buffer.IndexOf('\u2018') > -1) buffer = buffer.Replace('\u2018', '\''); // left single quotation mark
if (buffer.IndexOf('\u2019') > -1) buffer = buffer.Replace('\u2019', '\''); // right single quotation mark
if (buffer.IndexOf('\u201a') > -1) buffer = buffer.Replace('\u201a', ','); // single low-9 quotation mark
if (buffer.IndexOf('\u201b') > -1) buffer = buffer.Replace('\u201b', '\''); // single high-reversed-9 quotation mark
if (buffer.IndexOf('\u201c') > -1) buffer = buffer.Replace('\u201c', '\"'); // left double quotation mark
if (buffer.IndexOf('\u201d') > -1) buffer = buffer.Replace('\u201d', '\"'); // right double quotation mark
if (buffer.IndexOf('\u201e') > -1) buffer = buffer.Replace('\u201e', '\"'); // double low-9 quotation mark
if (buffer.IndexOf('\u2026') > -1) buffer = buffer.Replace("\u2026", "..."); // horizontal ellipsis
if (buffer.IndexOf('\u2032') > -1) buffer = buffer.Replace('\u2032', '\''); // prime
if (buffer.IndexOf('\u2033') > -1) buffer = buffer.Replace('\u2033', '\"'); // double prime
