NCBI SGML entity list

This is the list of SGML entities (ISO 8879) that we can currently parse. If you require a character that is not on the list, please e-mail us at pubmed@ncbi.nlm.nih.gov.

Note! If an ASCII character is sufficient to represent the entity in your text, please use the ASCII character. Use the SGML entities below only when ASCII will not suffice, or if you employ them already and it would be burdensome to translate them.
