===Possible errors===
* The template produces an {{error|Error-message|tag=span}} when parameter #1 (hex value) is missing.
* A non-hexadecimal input like ''00G9'' produces an error (Because ''G/g'' is not hexadecimal).
* Do not add the U+-prefix like ''U+00A9''. It will not be recognised.
* If the template ''only'' shows the code point number, like "{{unicode|2038}}", you're probably using the wrong template {{tlb|unicode}}, instead of {{tlb|unichar}}.
* The glyph may be overruled and changed into a ''label'' like <control-0007>. These characters have no Unicode name. An nlink will be directly to the article (entered in "nlink=Bell signal"). A blank like this "nlink=", (which links fine for regular characters like Pound sign), cannot work for <labeled> characters (there is no character name at all to make into a link). This produces an error.
* A decimal value input like ''1=98'' will be read as being hexadecimal value 0098. There is ''no way'' that the template can detect you intended to enter 98<sub>10</sub>=62<sub>16</sub>.No warning is issued, and the wrong character, U+0098<sub>16</sub>, will be shown (''not'' U+0062).
