 <h2>Displaying personal annotation data in the Genome Browser</h2>
 <p>
 <h6>How do I display my own personal annotation data in the Genome Browser?</h6>
 <p> 
 To create an annotation track that will display on the Genome Browser, you must first organize your 
 data into a format supported by the browser custom track feature:

 <h6>Can I upload a custom track with chromosome names (e.g. '1' or 'NC_000001.11') that don't
 match the UCSC-style chromosome names (e.g. 'chr1', 'chrX')?</h6>
 <p>
 As of 2018, you can upload a custom track that contains either
 UCSC-style chromosome names (e.g. 'chr1', 'chrX') or one of several supported
 aliases, typically from Ensembl (e.g. '1' or 'X'), GenBank (e.g. 'CM000663.2'
 or 'CM000685.2'), or RefSeq (e.g. 'NC_000001.11' or 'NC_000023.11'). Many
 different custom track types support this, including BED, BAM, and any of
 our big* formats like bigBed or bigWig. You can view the list of supported
 aliases by clicking on the &quot;View sequences&quot; link for your assembly of
 interest from the <a href="../cgi-bin/hgGateway">Assembly Gateway page</a> or
 as a &quot;chromAlias.txt&quot; file from <a
 href="https://hgdownload.soe.ucsc.edu/downloads.html" >our downloads server</a>
 under the link &quot;Genome sequence files and select annotations&quot; for that assembly.

+<h2>Apostrophes and special characters in track labels</h2>
+<h6>How can I put an apostrophe in my track label?</h6>
+<p>
+The Genome Browser supports a limited set of characters in the track image. In
+addition to the characters <code>a-z</code> and <code>A-Z</code>, it supports
+some accented characters such as <code>&eacute;</code> or <code>&aacute;</code> and apostrophes,
+specifically "<code>&#697;</code>" (which corresponds to Unicode character U+2019).
+If there are characters in your track's short or long label that we don't
+currently support, <a href="../contacts.html">contact us</a>.
