javascript - Add new alias for unicode character to HTML/CSS -

-

i trying write documents web have special characters in them.

there's few unicode characters not have "named character reference" include in web pages. example, here's funky arrow:

0000 21fb rightwards arrow double vertical stroke

which looks this: ⇻

if want make habit of this, need keep big list handy shows these characters , equivalent hex codes. easier if link css or javascript file, , type "alias" instead (similar named character reference). in other words, i'd able this:

<p>here arrow:  &my-special-arrow; </p>

can suggest way easily?

i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.
